AUSTIN (LN) — The Texas Supreme Court on Thursday wiped out a wrongful-death lawsuit against Bell Helicopter Textron Inc. over a 2017 Gulf of Mexico crash, ruling that a series of routine flight-manual revisions did not restart the General Aviation Revitalization Act's 18-year statute of repose and establishing binding precedent on how courts must apply the law's so-called rolling provision.
Pilot Matthew Kawamura died on February 27, 2017, when a loose engine cowling on a Bell helicopter — manufactured and delivered in 1997, twenty years before the crash — allegedly detached mid-flight, struck the tail rotor, and sent the aircraft into an uncontrollable descent. Kawamura had reported the problem after landing at an offshore platform in the Gulf of Mexico; Westwind Helicopters, his employer, directed him to fly back alone anyway.
His family sued Bell in October 2017, but the mechanical component at issue — the engine cowling and its fasteners — was original to the aircraft, placing the suit squarely outside GARA's 18-year window. To get around that bar, the family's experts, producing their first liability theory in February 2024, focused not on the cowling itself but on the flight manual: the preflight checklist told pilots to confirm the engine cowling was "Secured" but never warned that flying with a loose cowling could be fatal.
Because Bell made fifteen sets of revisions to the manual between 2002 and 2016 — including a 2011 revision to a preflight-check graphic, a non-substantive 2011 revision to the left-side fuselage check, and 2013 revisions to the oil-level and combustion-case instructions — the family argued the entire preflight-check subsection had been replaced by a "new" part, resetting the clock under GARA's rolling provision.
Chief Justice James Blacklock, writing for the court, rejected that theory in terms that leave little room for future maneuvering. The rolling provision, he wrote, requires identifying a specific part that is both "new" and "alleged to have caused" the injury — and a plaintiff cannot "cobble together its claim" by pointing to new parts that caused nothing and a causally relevant part that was never changed. The engine-cowling instruction is alleged to have caused the accident, but it is not new. The revised instructions are new, but they are not alleged to have caused anything.
The court drew on a line of federal decisions to anchor the ruling. Quoting the Ninth Circuit's decision in Caldwell v. Enstrom Helicopter Corp., Blacklock wrote that just as the installation of a new rotor blade does not start the 18-year period of repose anew for purposes of an action for damages due to a faulty fuel system, a revision to any part of the manual except that which describes the fuel system would be irrelevant. The Sixth Circuit's 2013 decision in Crouch v. Honeywell International, the court added, reached the same conclusion when plaintiffs similarly relied on a theory of continued omission rather than any specific harmful revision.
The court also addressed the family's implicit premise that the preflight-check subsection should be treated as a single undifferentiated unit, such that touching any part of it restarts the clock for all of it. That reading, Blacklock wrote, finds no support in GARA's text or in any decided case: Replacing one small part of a larger component or system does not replace the entire component or system containing the part. A new bolt merely replaces an old bolt. It does not yield a new engine that replaces the old engine.
On the question of mandamus — the procedural vehicle Bell used after the trial court denied summary judgment without explanation and the Houston Fourteenth Court of Appeals denied relief without a substantive opinion — the court held that forcing a manufacturer to litigate a suit Congress said may not be brought inflicts an injury no post-trial appeal can repair, citing its own 2021 decisions in In re Academy, Ltd. and In re Facebook, Inc. as controlling the analysis.
The district court is directed to grant Bell's motion for summary judgment; the writ will issue only if it does not comply.
The ruling forecloses what had been the aviation plaintiffs' bar's most durable workaround to GARA's repose period — the argument that incremental manual updates aggregate into a wholesale replacement of the document — in a jurisdiction that hosts substantial offshore aviation litigation tied to Gulf of Mexico oil operations.
