Abstract
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.
