Surprise NPRM Announcement Shocks Bonanza, Navion Owners
As you may have already seen in today's edition of Aero-News, on
Wednesday the FAA submitted a Notice of Proposed Rulemaking on a
potential Airworthiness Directive aimed at McCauley C406 and C409
propellers mounted to Teledyne Continental Motors (TCM) IO-520,
TSIO-520, or IO-550 reciprocating engines. The news came as a shock
to the AOPA's Luis Gutierrez, who is Director of Regulatory and
Certification Policies for the organization.
