Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. This proposed AD was prompted by a report that a flight deck emergency escape hatch was difficult to open due to the hose ends being connected to the hatch with incorrect parts, which could affect drainage of the hatch. This proposed AD would require inspection of the flight deck emergency escape hatch drain hose for discrepancies and applicable corrective actions, and prohibit accomplishment of maintenance actions using the instructions of certain maintenance tasks, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
