The Saturday afternoon peak at a trampoline park in City of Fort Worth is a precisely engineered environment. From the bright neon branding of chains like Urban Air, Altitude, and Sky Zone to the pumping music and the smell of concession-stand pizza, every element is designed to produce high-throughput family entertainment. But beneath the surface of this business model lies a series of calculated decisions—decisions about staffing ratios, maintenance budgets, and corporate liability shielding—that prioritize margin over the safety of your child.

When your child is airborne at a facility in City of Fort Worth, they are participating in an activity that the American Academy of Pediatrics (AAP) has formally advised against since 1999. Since then, the AAP has reaffirmed its position in 2012 and again in 2019, stating plainly that trampolines should not be used for routine recreational purposes. Yet, the industry has exploded in North Texas, with Urban Air’s corporate headquarters just a few miles away in Grapevine and Altitude Trampoline Park based right here in Fort Worth.

At Attorney911, we know that what the industry calls a “freak accident” is almost always the predictable output of a systemic failure. We are not just another personal injury firm; we are a dedicated catastrophic injury practice led by Ralph Manginello, who brings over 25 years of courtroom experience and federal court admission to every case. Our team includes associate attorney Lupe Peña, a former insurance defense lawyer who used to represent the very carriers and recreational businesses we now sue. He didn’t just read their playbook; he helped write it. He knows which waiver clauses are built to crumble in a Texas courtroom and which insurance layers the adjusters are instructed to hide.

If your family’s life changed in a split second on a City of Fort Worth jump court, you don’t need a lawyer who “handles accidents.” You need a firm that has memorized ASTM F2970, that understands the biomechanics of a growth plate injury, and that has the resources to take on the private equity giants behind the major chains. We are that firm.

Call 1-888-ATTY-911 (1-888-288-9911). We answer 24/7. Hablamos Español.

The Forensic Reality: Why 72 Hours in City of Fort Worth Determine Success

In the immediate aftermath of a catastrophic injury at a City of Fort Worth trampoline park, the family is rightfully focused on the trauma bay at Cook Children’s Medical Center or the pediatric orthopedic surgical suite. While you are focused on your child, the park’s risk management team is focused on the evidence.

The evidence clock in a City of Fort Worth trampoline case runs faster than any other personal injury vertical. Most commercial trampoline park DVR surveillance systems are set to overwrite on a 7-to-30-day rolling cycle. If you wait three weeks to contact a City of Fort Worth trampoline injury lawyer, the video of the incident—the most critical piece of evidence in proving an attendant was on their phone or that a court was overcapacity—may be gone forever.

Furthermore, the waiver kiosk databases used at many City of Fort Worth locations are known to purge or “update” version histories on cycles as short as 72 hours. The incident report filled out by a shift lead the night of the injury is often “revised” within 48 hours to sanitize admissions of fault. At Attorney911, our spoliation and preservation-of-evidence protocol is immediate. Within 24 hours of being retained, we send a formal litigation hold via certified mail, email, and fax to the park, its franchisor (whether that is Sky Zone, Inc., Unleashed Brands, or Altitude Franchise Holdings), and their insurance carriers.

We don’t just ask them to “save the video.” We demand the original native-format files, the DVR hardware itself, access logs showing who viewed or exported footage, and the metadata for every version of the incident report. We don’t draft these demands from a blank page; we deploy paralegal-grade scaffolds that have been refined through decades of complex litigation, including Ralph Manginello’s experience in the BP Texas City refinery litigation against multi-national corporate defense teams.

In City of Fort Worth, the difference between a six-figure settlement and a zero-recovery “dismissal based on waiver” is often what happens in the first three days. We stop the clock. We freeze the evidence. We build the case while the park is still hoping you won’t call.

Don’t let the evidence disappear. Call 888-ATTY-911 today.

The Physics of Failure: Anatomy of a City of Fort Worth Trampoline Accident

When people think of trampoline injuries, they often imagine a child falling off the edge. But the data tells a different story. According to the CPSC’s NEISS database, which tracks over 300,000 trampoline-related ER visits annually, the majority of catastrophic injuries happen ON the trampoline bed itself.

The Double-Bounce: A Catapult for Catastrophe

The signature injury mechanism at parks in City of Fort Worth is the double-bounce. This occurs when a heavier jumper lands on the bed at the same instant a lighter jumper is pushing off. The trampoline bed acts as a kinetic energy transfer device, multiplying the launch force of the smaller child by up to 4x.

The physics are devastating. A 200-pound adult doesn’t just “jump” with a 50-pound child; the adult becomes a catapult and the child becomes a projectile. This is exactly why ASTM F2970, the industry standard written by the trampoline parks themselves, requires operators to operationalize age and weight separation. When a City of Fort Worth park ignores these ratios to maximize Saturday afternoon revenue, they are choosing to allow a known biological weapon—kinetic energy transfer—to be used against children.

Foam Pits: The Illusion of Softness

Many City of Fort Worth families believe foam pits are the safest part of the park. Biomechanically, they can be the most dangerous. In 2012, Ty Thomasson tragically lost his life after a backflip into a foam pit at SkyPark in Phoenix because the pit was only 2 feet, 8 inches deep instead of the recommended 6 feet. This incident led to “Ty’s Law” in Arizona, the first state-level regulation of the industry.

In City of Fort Worth, if a foam pit is compacted through heavy use and hasn’t been “fluffed” or refilled to spec, a child entering head-first or feet-first will “bottom out” against the hard floor beneath. This axial loading is the primary cause of cervical spinal cord injuries and paralysis. We’ve seen cases where a foam pit wasn’t a foso de espuma at all, but merely a thin layer of cubes over a “dense foam pad.”

Harness and Attraction Failures

As City of Fort Worth parks pivot to becoming Family Entertainment Centers (FECs), they are bolting on climbing walls, Sky Rider ziplines, and ropes courses. The 2019 death of 12-year-old Matthew Lu at an Altitude park in North Carolina serves as a grim warning: he fell 20 feet onto concrete because an employee failed to properly secure his harness. The park publicly admitted “human error” and removed the attraction—a structural admission of a failed safety system.

Similarly, Urban Air has seen a recurring chain-wide pattern of Sky Rider zipline strangulations, from Newnan, Georgia to Illinois. These are not isolated “accidents.” They are design defects and staffing failures that we subpoena on a chain-wide basis under Federal Rule of Evidence 404(b) to prove notice and foreseeability.

Breaking the Paper Shield: Our Texas Waiver-Defeat Strategy

The first thing every insurance adjuster will tell a City of Fort Worth parent is: “You signed a waiver. You have no case.” At Attorney911, our response is: “Let’s read that waiver against Texas law.”

In Texas, a waiver is not a wall; it is a hurdle, and often a very short one. We deploy a multi-vector attack on every City of Fort Worth trampoline waiver:

  1. The Munoz Doctrine: Under the landmark Texas case Munoz v. II Jaz, Inc. (1993), a parent generally cannot sign away a minor child’s personal injury claim against a commercial operator. While a parent’s signature might bar the parent’s own derivative claims (like reimbursement for medical bills), the child’s direct cause of action for their own pain, suffering, and impairment remains intact in Texas.
  2. Gross Negligence Carve-Out: Texas law, anchored in Moriel and § 41.003 of the Civil Practice and Remedies Code, does not allow a waiver to release a defendant from “gross negligence.” If we can prove the park had subjective awareness of an extreme risk (like a torn mat or understaffed court) and chose to disregard it, the waiver is void. Our Houston jury verdict in the Cosmic Jump case—where we achieved $11.485 million despite a signed waiver—proves this works.
  3. The Dresser Fair Notice Rule: Per Dresser Industries, Inc. v. Page Petroleum, a Texas waiver must be conspicuous. It must use the exact word “negligence” and must be printed in a way that would attract a reasonable person—bold, all caps, or contrasting color. Many City of Fort Worth kiosk waivers buried in a 20-page scroll fail this test.
  4. The Delfingen Spanish Language Attack: Texas has a large and vibrant Hispanic community. If your family’s primary language is Spanish and you were pressured to click an English-only waiver at a City of Fort Worth park without an explanation in your native tongue, the Delfingen doctrine allows us to challenge the very formation of that contract. Lupe Peña speaks with our Spanish-speaking clients directly to build this specific defense.
  5. Signer Authority (Texas Family Code § 153.073): Often in DFW, a grandmother, an aunt, or a family friend takes the kids to the park and signs the iPad. Under Texas law, only a legal guardian or conservator has the authority to bind a minor. If the wrong person signed, the waiver is a legal nullity.

You signed a piece of paper, not your rights away. Call 1-888-ATTY-911 and let us take apart the waiver.

Medical Mastery: Protecting Your Child’s Future in City of Fort Worth

A “broken bone” in a City of Fort Worth eight-year-old is not the same as a broken bone in an adult. Because pediatric bones are still developing, trampoline accidents often involve the growth plates (physes).

Salter-Harris Fractures and Growth Arrest

A Salter-Harris Type II fracture of the distal tibia can result in “growth arrest.” This means the bone may stop growing or grow at an angle, resulting in a permanent limb-length discrepancy that doesn’t fully manifest until puberty—years after the initial trampoline accident. In City of Fort Worth, we work with pediatric orthopedic surgeons to monitor these injuries through skeletal maturity. We don’t calculate your damages based on today’s ER bill; we calculate them based on the next decade of potential corrective surgeries and lifelong gait complications.

SCIWORA: The Invisible Spinal Injury

Spinal Cord Injury Without Radiographic Abnormality (SCIWORA) is a pediatric phenomenon where the spinal cord is stretched or damaged even when X-rays and CT scans appear normal. A child who lands head-first in a City of Fort Worth foam pit and complains of a “stiff neck” might be in the early stages of a catastrophic cord event. Parks that don’t train monitors to recognize SCIWORA are gambling with your child’s ability to walk.

Rhabdomyolysis: The Under-Reported Emergency

Extended jumping for 60 to 90 minutes in a hot, crowded City of Fort Worth indoor park can lead to exertional rhabdomyolysis—a breakdown of muscle tissue that releases myoglobin into the blood, leading to acute kidney failure. Dark, cola-colored urine 24 hours after a park visit is a medical emergency.

Our firm is uniquely equipped to handle these cases. We are currently litigating a $10 million lawsuit against the University of Houston and Pi Kappa Phi for rhabdomyolysis and kidney failure. The medical experts, the biochemistry of the myoglobin cascade, and the institutional-accountability theories we use in that $10 million case are the exact same ones we deploy for City of Fort Worth trampoline rhabdo victims.

The Corporate Archeology of a City of Fort Worth Lawsuit

“Sky Zone” or “Urban Air” are not just single companies. They are multi-layered corporate stacks engineered to frustrate litigation. To recover the compensation your child deserves, we must perform corporate archeology on the 5-layer defendant stack:

  1. Operator LLC: Often undercapitalized, this is the entity that actually runs the City of Fort Worth park.
  2. Franchisee: The multi-unit owner who may operate several locations across North Texas.
  3. Franchisor: The brand giant (Sky Zone Franchising LLC or Urban Air Franchise Holdings) that mandates the training and safety standards.
  4. Corporate Parent: Sky Zone, Inc. (f/k/a CircusTrix) or Unleashed Brands, often backed by private equity sponsors like Palladium Equity Partners or Seidler Equity.
  5. Private Equity Sponsor: This is where the decisions to cut staffing ratios and defer maintenance are often made to hit margin targets.

While a local park might claim their insurance policy is only $1 million, our discovery protocol reaches the corporate excess towers, the franchisor’s additional-insured coverage, and the product liability policies of the equipment manufacturers. We have gone toe-to-toe with Fortune 500 corporations like BP, Amazon, and Walmart. The corporate fleets of lawyers at a national trampoline chain don’t intimidate us; we’ve beaten them before.

What Fair Compensation Looks Like in City of Fort Worth

A trampoline injury settlement isn’t just about paying back the health insurance company. It is about a Pediatric Life-Care Plan. For a City of Fort Worth child with a permanent injury, we forecast:

  • Future Medical Care: Annual specialist visits, hardware removal surgeries, and corrective osteotomies.
  • Educational Accommodations: Specialized tutoring and IEP support if a TBI has affected academic performance.
  • Lost Earning Capacity: Using forensic economists to calculate how a childhood injury will impact their adult lifetime earnings.
  • Non-Economic Damages: The trauma, the nightmares, the inability to play City of Fort Worth youth sports, and the permanent disfigurement of surgical scars.

As client Glenda Walker said, “They fought for me to get every dime I deserved.” We treat our clients like family, a sentiment echoed by Chad Harris: “You are NOT just some client… You are FAMILY to them.”

Frequently Asked Questions for City of Fort Worth Families

Does it cost anything to hire Attorney911 for a City of Fort Worth trampoline case?

No. We work on a 100% contingency fee basis. This means we advance every cost—the biomechanical engineers, the orthopedic consultants, and the digital forensics experts. If we don’t win your case, you owe us nothing. Your child’s recovery fund stays untouched.

How long do I have to sue a trampoline park in City of Fort Worth?

In Texas, the statute of limitations for personal injury is generally two years. However, for a minor, the clock is “tolled” until they turn 18, theoretically giving them until their 20th birthday to file. But waiting is a catastrophic mistake. The evidence in City of Fort Worth trampoline cases (video, logs, and witness memories) disappears in weeks, not years. You must act now to preserve the case.

My child was hurt at a birthday party, and I didn’t sign the waiver—the host parent did. Does that matter?

Yes. It potentially voids the waiver defense entirely. Under Texas law, a host parent cannot sign away the legal rights of someone else’s child. This is a common “waiver gap” that we exploit to bypass arbitration and go straight to a City of Fort Worth jury.

What is a “trampoline fracture”?

Physicians use this term to describe a specific buckle fracture of the proximal tibia metaphysis, typically occurring in children under 6 who are “double-bounced” by a heavier jumper. Because children under 6 have bones that are not yet fully ossified, they should never be on a trampoline. A City of Fort Worth park that markets “Toddler Time” to this age group is affirmatively inviting this specific injury.

What happens if the City of Fort Worth park’s surveillance video is “missing”?

We don’t take “it’s missing” as an answer. We subpoena the DVR hard drive, the retention logs, and the access history. In a Georgia case (Mathew Knight), a jury awarded $3.5 million after the park’s video glitched on four cameras simultaneously at the moment of injury. Jurors do not like it when parks hide evidence, and neither do we.

Can I sue the manufacturer of a backyard trampoline in City of Fort Worth?

Yes. If your backyard trampoline failed due to a manufacturing defect (like a broken weld) or a design defect (like a net that UV-degrades in the Texas sun), you may have a strict product liability claim. We look at the CPSC recall histories for brands like Jumpking, Skywalker, and Bouncepro to prove the manufacturer knew the product was dangerous.

We are not U.S. citizens—can we still file a lawsuit in City of Fort Worth?

Yes. Your immigration status has no bearing on your right to seek justice for your injured child in a Texas court. Our communications are privileged and confidential. Lupe Peña can discuss this with you in Spanish (Hablamos Español) to ensure your family feels safe and protected throughout the process.

The Closing Kill-Shot: The Clock Is Running in City of Fort Worth

What happened to your child at an Urban Air, Sky Zone, or Altitude park wasn’t an accident; it was the predictable output of a systemic failure. The AAP has been warning about these risks since 1999. The industry wrote ASTM F2970 to set a safety floor, and then most parks in City of Fort Worth chose to operate beneath it to save on labor costs. Their waivers were drafted by lawyers to make you feel defeated before you start. Their surveillance is engineered to overwrite before you even have a follow-up appointment.

Attorney911 was built for exactly this fight. Ralph Manginello brings 25+ years of catastrophic injury experience. Lupe Peña used to defend these parks—now he knows how to dismantle them. Our active $10 million rhabdomyolysis case against the University of Houston gives us a medical-litigation edge no other firm can match.

Your child’s case is decided by what gets preserved this week. The DVR overwrites in 7 to 30 days. The waiver kiosk database purges. The attendants transfer. The incident report gets “revised.”

Call 1-888-ATTY-911. Hablamos Español. No fee unless we win. We advance every expense—the biomechanist, the pediatric orthopedic surgeon, the ASTM compliance specialist. Your child’s recovery fund stays intact. Our spoliation letter goes out within 24 hours of your retention.
