Cracks And Malfunctions
During an accident investigation, the top l/h engine cowling was found with evidence of fire damage. The l/h exhaust manifold pipe was loose and the l/h turbocharger clamp was lying in the bottom of the engine cowl. This aircraft was destroyed in fire, sustaining one fatality. Exhaust clamp p/n: MVT69183200LW1. The engine was a Lycoming TIO-540-J2B, presumably installed under an STC.
Key Takeaways:
- A fatal aircraft fire occurred in a Beech A36 due to a loose exhaust manifold pipe and turbocharger clamp, while a Lycoming O360-A4M experienced an in-flight engine failure from a cracked crankshaft, and Rotax 912ULS fuel system components rapidly failed when exposed to 10% ethanol fuel.
- An aviation school identified a widespread issue of Airhawk tires chafing and grooving the inner rims of wheel assemblies on multiple Piper PA28-181 aircraft, requiring extensive replacements.
- Newly installed, Kelly-overhauled turbochargers repeatedly developed leaking oil seals within minimal flight time, necessitating successive replacements on a Piper PA-34-200T.
