Airworthiness Directive 2010-16-08
one-timeAirworthiness Directives; Schweizer Aircraft Corporation (Schweizer) Model 269D Helicopters
What this AD requires
This amendment adopts a new airworthiness directive (AD) for the Schweizer Model 269D helicopters. This action requires installing a Scroll Housing Blade Containment Shielding Kit on each helicopter. This amendment is prompted by 21 reports of the blades of the oil cooler impeller separating, one of which punctured the engine and transmission oil cooler resulting in loss of engine oil pressure. The actions specified in this AD are intended to protect the oil cooler from uncontained oil cooler impeller blades that could damage the oil cooler and result in loss of engine and transmission oil pressure, and subsequent loss of control of the helicopter.
Which aircraft AD 2010-16-08 applies to
Applicability depends on the aircraft’s type certificate — check it against the specific tail.
Whether AD 2010-16-08 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
