Description

The FAA proposes to supersede Airworthiness Directive (AD) 2015-07-03 for certain Cessna Model 402C and 414A airplanes. This proposed AD addresses additional reports of cracking and multi-site cracking in engine beams that are difficult to access. It requires repetitive inspections of the engine beam for cracks, applicable on-condition actions, and adds a new life-limit to affected engine beams requiring replacement when the life-limit is reached. The purpose is to prevent failure of the engine beam, which could result in engine separation, loss of power, and loss of control of the airplane.
