Summary
This action withdraws a notice of proposed rulemaking (NPRM) that proposed an airworthiness directive (AD) supersedure, applicable to Honeywell International Inc. TPE331-10 and TPE331-11 series turboprop engines. That action would have required adding 360 first stage turbine disk serial numbers (S/Ns) to the applicability. Since we issued that NPRM, we decided not to supersede AD 2009-17-05, but instead to issue a new NPRM for those additional 360 parts. Accordingly, we withdraw the proposed rule.
