AD 2025-01-04 Airworthiness Directives; DAHER AEROSPACE (Type Certificate Previously Held by SOCATA) Airplanes

Makes named: daher, socata. Models named: TBM 700. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to DAHER AEROSPACE (type certificate previously held by SOCATA) (DAHER) Model TBM 700 airplanes, all serial numbers, certificated in any category, except those with DAHER Modification (MOD) 70-0777-27 installed during production.

Comply with this AD within the compliance times specified, unless already done.

(1) Clean and lubricate the left-hand (LH) and right-hand (RH) internal actuator rods in accordance with Paragraph C. in the Description of Accomplishment Instructions of Daher Aerospace Service Bulletin SB 70-118 Revision 3, dated December 2023 (Daher SB 70-118) within the compliance times identified in paragraph (g)(1)(i) or (ii) of this AD, whichever occurs later. (i) Before the accumulation of 400 hours time-in-service (TIS) or 12 months, whichever occurs first, since the first installation of a LH and RH inner flap actuator, and thereafter at intervals not to exceed 400 hours TIS or 12 months, whichever occurs first. (ii) Within 10 hours TIS after the effective date of this AD and thereafter at intervals not to exceed 400 hours TIS or 12 months, whichever occurs first. (2) Within the compliance time identified in paragraph (g)(2)(i) or (ii) of this AD, whichever occurs later, and thereafter, at intervals not to exceed 400 hours TIS or 12 months, whichever occurs first, for each inner flap actuator, measure the play between the drive nut and the internal actuator rod in accordance with Section A, Paragraphs (1) through (9), in the Description of Accomplishment Instructions of Daher SB 70-118. Where Section A, Paragraph (3), in the Description of Accomplishment Instructions of Daher SB 70-118 specifies “With the help of a second operator” this AD requires this action be performed by persons authorized under 14 CFR 43.3. (i) 3,000 hours TIS since first installation of the inner flap actuator on your airplane. (ii) 400 hours TIS or 12 months, whichever occurs first since the last play measurement accomplished for that inner flap actuator in accordance with Section A, Paragraphs (1) through (9), in the Description of Accomplishment Instructions of Daher SB 70-118. (3) If, during any measurement required by paragraph (g)(2) of this AD, any play is found, as identified in Section A, Paragraphs (8)(b) and (9)(b), of the Description of Accomplishment Instructions, Daher SB 70-118, before further flight, accomplish the applicable corrective actions in accordance with Section A, Paragraphs (10) through (15) and (17), and Section C, Paragraph (1), in the Description of Accomplishment Instructions of Daher SB 70-118. Where Section B, Paragraph (4), in the Description of Accomplishment Instructions of Daher SB 70-118, specifies to discard an old drive nut, this AD requires removing the old drive nut from service. (4) If, during any measurement as required by paragraph (g)(2) of this AD, no play is found, as identified in Section A, Paragraphs (8)(a) and (9)(a), in the Description of Accomplishment Instructions of Daher SB 70-118, before further flight, accomplish the actions in accordance with Section A, Paragraphs (13) through (15) and (17), and Section C, Paragraph (1), in the Description of Accomplishment Instructions of Daher SB 70-118.

This AD was prompted by reports of wear of the inner flap actuator drive nut. The FAA is issuing this AD to prevent wear of the drive nut threading on the internal actuator flaps. The unsafe condition, if not addressed, could result in improper play between the actuator threaded rod and the drive nut, which could result in loss of flap control and consequent reduced or loss of control of the airplane.

None.
