FAA Orders Muffler Checks on Tecnam Planes to Avoid Engine Drama
Published Date: 4/3/2026
Rule
Summary
If you own a Tecnam P2010 airplane, listen up! The FAA found a problem that could cause engine power loss, so they’re requiring regular inspections and repairs of the exhaust muffler flame tube starting April 20, 2026. Fixing this keeps your plane safe and flying, and there’s an option to stop inspections once the repair’s done. Comments are open until May 18, 2026, so don’t miss your chance to weigh in!
Analyzed Economic Effects
4 provisions identified: 2 benefits, 2 costs, 0 mixed.
Required borescope inspections and repairs
If you own or operate a Tecnam P2010 (serial numbers up to 335) with a Lycoming IO-390 engine, you must do a detailed borescope inspection (BSI) of the exhaust muffler flame tube within 25 hours time-in-service (TIS) or 30 days after April 20, 2026, whichever comes first, and then at intervals not to exceed 200 hours TIS. If cracks or fracture initiation are found, you must repair the flame tube using an FAA-, EASA-, or Tecnam DOA-approved method before further flight.
Optional terminating maintenance program revision
You can stop the repetitive BSI and repair requirements by revising your aircraft maintenance program to include TECNAM P2010 AMM Supplement S6, Ed. 2, Rev. 2, dated January 8, 2026. The AD lists this revision as an acceptable method to comply with the inspection and repair paragraphs.
Special flight permits prohibited
The AD states that special flight permits under 14 CFR 21.197 and 21.199 are not allowed for affected P2010 airplanes, meaning you may not be able to fly the airplane under a special permit to a repair location.
Credit for earlier compliant inspections
If you already performed the required inspections before April 20, 2026 using TECNAM Service Bulletin SB 937-CS-Ed. 1, Rev. 0 (dated September 16, 2025) or SB 937-CS-Ed. 2, Rev. 0 (dated January 7, 2026), you may take credit for those actions toward compliance with this AD.
