Update

The pilot of the 9/7 A36 inflight catastrophic engine failure, which had reported separation of all six cylinders in flight, reports engine investigators learned this was caused by a:

...failed reducer fitting [an oil line that is part of an aftermarket turbo normalizing system].  The hose...supplies the turbo for its oil feed and the hose connecting straight out the rear is for the wastegate operation.

When this fitting broke, the wastegate no longer had any control to maintain [manifold pressure] and that’s why [the pilot] first experience[d] MAP fluctuations.  The oil pump then pumped all the oil overboard out this open port, there was no lubrication for any internals of the engine, and this is why it threw almost all the connecting rods at the about same time.


New reports this week

10/13 1820Z (1420 local Saturday afternoon): A Be33 “ran off the runway, hit a sign and broke [its] landing gear,” during arrival at Reidsville, Georgia. The solo pilot reports no injury and airplane damage is “unknown”. N9469Q (CE-369) is/was a 1972 F33A registered in Savannah, Georgia.

("Loss of directional control during landing”)

10/16 1619Z (1219 local Tuesday afternoon): All five occupants of a Be58 escaped injury when the airplane landed gear up at Mansfield, Ohio. Airplane damage is “minor”. N700ST (TH-1091) is/was a 1980 Baron 58 registered in Shelby, Ohio.

(“Gear up landing”—“minor” damage in this context includes replacing two propellers, tear-dwon, repair as necessary and reassemble two engines, and miscellaneous sheet metal and antenna replacement work. The cost of all this frequently turns “minor” gear-up damage into a “totaled” airplane).


New NTSB reports this week

Events previously reported in the Weekly Accident Update

9/17 fatal F33A engine failure at Cottonwood, Arizona. Was it a fuel starvation event? I’m interested to learn in what position the NTSB found the airplane’s fuel selector. The preliminary report doesn’t tell us.

10/1 fatal V35 loss of control inflight during landing at La Verne, California. Could wake turbulence have been a factor?

 Part 91 as an instructionaler.
