Summary
We are revising an NPRM for SOCATA Model TBM 700 airplaness (type certificate previously held by EADS SOCATA) that was proposed to revise AD 2007-04-13. 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 cracks found on the main landing gear cylinders. This action revises the NPRM by including the actions against those airplanes that reach a certain number of landings after the effective date of the AD. We are proposing this supplemental NPRM (SNPRM) to correct the unsafe condition on these products. Since this action imposes an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on this proposed change.
