McDonnell Douglas Helicopter Company and Hughes Helicopters, Inc. Issue Airworthiness Directive for Model 369 Helicopters

The companies are issuing an airworthiness directive to address tail rotor blade abrasion strip debonding, following an accident caused by the separation of an abrasion strip from a tail rotor blade and subsequent tail rotor separation. The directive requires daily preflight checks and 100 hours time-in-service inspections until rivets are installed to secure the abrasion strip.
