EASA Orders a One-Time Inspection of Listed TBM 700 Gear Barrels

News. EASA has issued AD 2026-0212, a final airworthiness directive for Daher Aircraft TBM 700 aeroplanes. It was issued on 4 November 2026 and is effective 18 November 2026. It does not supersede another AD. The type-certificate data sheet is EASA.A.010. The subject is ATA 32, landing gear, main-landing-gear barrel inspection.

The directive applies to TBM 700 aeroplanes of all manufacturer serial numbers. The inspection itself is limited to aeroplanes that have an affected barrel installed. The PDF is EASA AD 2026-0212. The interim publications list dated 5 November 2026 carries the same number, issue date and effective date.

Which barrels are affected

An affected part is a main-landing-gear barrel whose serial number is in Appendix 1, installed as part of main-landing-gear part number D23767001-2 or D23768001-2, except a barrel that has already passed an inspection under Daher Service Bulletin 70-366-32 with no crack detected. A serviceable part is any main-landing-gear barrel eligible under approved Daher instructions that is not an affected part. Group 1 aeroplanes have an affected part installed. Group 2 aeroplanes do not.

Appendix 1 lists eight left-hand barrel serial numbers and twelve right-hand barrel serial numbers. Note 3 says the left-hand and right-hand gear part numbers, and the main-landing-gear serial numbers, are provided for information only.

EASA says cracks in the main-landing-gear barrel have been reported in service, and that investigation found a manufacturing non-conformity in the area of the forging joint line of barrels installed in the left-hand or right-hand gear, or both. If not detected and corrected, EASA says that condition could lead to fatigue cracks, a collapsed main landing gear during the take-off or landing run, and a possible reduction in structural integrity.

The inspection clock

For Group 1, paragraph (1) requires a one-time inspection of each affected part under Service Bulletin 70-366-32. The compliance time is the later of A and B in Table 1.

• A. Within 12 months, or before exceeding 200 landings, whichever occurs first, since the last annual inspection.
• B. Within 3 months after the effective date, 18 November 2026.

Note 1 changes the calculation when, on the effective date, the annual inspection has never been accomplished or was last accomplished more than 12 months earlier. In that case the inspection is due within 3 months after the effective date, or within 12 months since the date of release of the aeroplane's EASA Form 52 or an equivalent statement of conformity, whichever occurs later.

If the inspection finds any crack, paragraph (2) requires replacement of that affected part with a serviceable part before next flight, in accordance with the service bulletin. The bulletin cited is the original issue dated August 2026. The AD does not print a day in August. Later approved revisions are acceptable.

Installation wording

Paragraph (3) applies to Group 1 and Group 2. From the effective date, EASA's sentence reads that it is allowed to install an affected part on any aeroplane provided that it is a serviceable part, as defined in the AD. Those definitions exclude a listed barrel from "affected part" once it has passed the bulletin inspection with no crack detected, and they define a serviceable part as a barrel that is not an affected part. Note 2 says removal of an affected part and reinstallation of that same part at the same location on the same aeroplane, during a single maintenance visit, is not an installation under paragraph (3).

EASA posted the text as PAD 26-106 on 15 September 2026 for consultation until 13 October 2026, and says the comment-response document is in the zipped file on this AD's record. A TBM 700 whose barrels are outside the table is Group 2: still within the type applicability, with no paragraph (1) inspection.
