Summary
This document proposes to revise an earlier proposed airworthiness directive (AD) that would apply to all British Aerospace Model HP.137 Jetstream Mk.1, Jetstream Series 200, Jetstream Series 3101, and Jetstream Model 3201 airplanes. The earlier NPRM would have required you to repetitively inspect the horizontal and vertical stabilizer attachment fittings and associated hardware for corrosion and wear (damage) and repair or replace any damaged parts. The earlier NPRM resulted from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The manufacturer has issued new service information that supersedes the service information specified in the NPRM and changes the procedures for doing the proposed inspections. These procedures impose an additional burden over that proposed in the NPRM. Therefore, we are reopening the comment period to allow the public the chance to comment on these additional actions.
