Notice of proposed rulemaking (NPRM).

We propose to adopt a new airworthiness directive (AD) for certain Ipeco Holdings Ltd. (Ipeco) pilot and co-pilot seats. This proposed AD was prompted by reports of unexpected movement of pilot and co-pilot seats on takeoff and landing. This proposed AD would require modification and reidentification of the affected seats. We are proposing this AD to correct the unsafe condition on these products.
