THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: AMEND AIRWORTHINESS DIRECTIVE (AD) 68-05-01 TO REQUIRE THAT AN INSPECTION OF THE MUFFLER AND EXHAUST SYSTEMS MEETING THE REQUIREMENTS OF THE AD BE PERFORMED DURING THE AIRCRAFT'S ANNUAL INSPECTION IF A DETAILED INSPECTION OF THE SYSTEM HAS NOT BEEN MADE DURING THE PRECEDING YEAR ON THE BASIS OF THE TIME-IN-SERVICE REQUIREMENTS OF THE AD.
In plain language (FlightFinder summary)
The National Transportation Safety Board asks the Federal Aviation Administration to update Airworthiness Directive 68-05-01 so that an inspection of the muffler and exhaust system is required during the aircraft's annual inspection if a detailed inspection has not been performed in the preceding year under the directive's time-in-service requirements.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
