Airworthiness Directive · Amendment 39-22928 · Te flap control system
DAHER AEROSPACE (Type Certificate Previously Held by SOCATA) Airplanes
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.
The FAA is adopting a new airworthiness directive (AD) for certain DAHER AEROSPACE (DAHER) Model TBM 700 airplanes. This AD was prompted by reports of wear of the inner flap actuator drive nut. This AD requires cleaning and lubricating the internal actuator rods, measuring the play between the drive nuts and the internal actuator rods, and if any play is found, replacing the drive nuts. This AD also allows replacing the drive nuts with certain other design drive nuts as terminating action for the requirements. The FAA is issuing this AD to address the unsafe condition on these products.
(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.
Replacing the drive nuts in accordance with Section B, Paragraphs (1) through (10), in the Description of Accomplishment Instructions of Daher SB 70-118, constitutes terminating action for all of the actions required by paragraphs (g)(1) and (2) of this AD, provided, after that replacement, no LH flap actuator having part number (P/N) 1-5295-B or RH flap actuator having P/N 2-5295-B is installed. 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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
