Summary
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
An A300-600 operator reported two events of IPECO pilot seat moved in the aft position, one during take-off roll and one during climb out. The investigation of these events showed that a broken/ missing spring contributed to the seat not being correctly locked. An unwanted movement of pilot or co-pilot seat in the aft direction is considered as potentially dangerous, especially during the take-off phase when the speed of the aeroplane is greater than 100 knots and until landing gear retraction. * * * * *
The unsafe condition is potential loss of control of the airplane during take-off and landing. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
