Summary

We are revising an earlier proposed airworthiness directive (AD) for certain Piper Aircraft, Inc. Model PA-31-350 airplanes. The NPRM proposed to require inspecting the fuel hose assembly and the turbocharger support assembly for proper clearance between them, inspecting each assembly for any sign of damage, and making any necessary repairs or replacements. The NPRM was prompted by a report of an engine fire caused by a leak in the fuel pump inlet hose. This action revises the NPRM by requiring the use of revised procedures in a new service bulletin. We are proposing this supplemental NPRM (SNPRM) to correct the unsafe condition on these products. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
