Airworthiness Directives; Costruzioni Aeronautiche Tecnam S.P.A. Airplanes
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The FAA is issuing a new airworthiness directive (AD 2026-07-05) for certain Tecnam Model P2010 airplanes equipped with Lycoming IO-390 engines, serial numbers up to 335. Prompted by reports of unrecoverable engine power loss due to 95% exhaust blockage from exhaust muffler flame tube disconnection, this AD mandates repetitive detailed borescope inspections (BSIs) of the flame tube. Initial inspection must occur within 25 hours time-in-service (TIS) or 30 days after April 20, 2026, effective date, then every 200 hours TIS. If cracks, fractures, or initiation evidence is found, repairs must follow FAA, EASA, or Tecnam DOA-approved methods. An optional terminating action ends repetitive inspections. This immediate final rule skips prior notice due to safety risks, with comments due by May 18, 2026. It affects 33 U.S.-registered airplanes, costing $170 per inspection and up to $2,840 per repair.
