M7 Aerospace LLC Airplanes
This AD applies to the following M7 Aerospace LLC airplanes, certificated in any category, as identified in table 1 of paragraph (c) of this AD:
| Model | Serial numbers |
|---|---|
| SA226-T | T265, T267 |
| SA226-T(B) | T(B)348 |
| SA226-TC | TC277 |
| SA226-AT | AT071, AT072, AT073 |
We are superseding Airworthiness Directive (AD) 2011-17-07 for certain M7 Aerospace LLC (type certificate previously held by M7 Aerospace LP) Models SA226-T, SA226-T(B), SA226-TC, and SA226-AT airplanes. AD 2011-17-07 required repetitive replacement and inspection of certain elevator, rudder, aileron, and aileron-to-rudder interconnect primary control cables, and checking and setting of flight control cable tension. This AD requires repetitively inspecting and replacing the primary flight control rudder cables, repetitively replacing all other primary flight control and trim tab cables, and checking/setting the flight control cable tension. This AD was prompted by a report of extensive damage found on the left hand primary flight control rudder cable located under the cockpit floor on one of the airplanes affected by AD 2011-17-07. We are issuing this AD to correct the unsafe condition on these products.
Unless already done, comply with paragraphs (g) through (k) of this AD. If the hours time-in-service (TIS) of the control cables cannot be positively determined by the logbook, then you must use hours TIS of the airplane to comply with the requirements of this AD.
Within the next 10 hours TIS after July 21, 2015 (the effective date of this AD) or within the next 60 days after July 21, 2015 (the effective date of this AD), whichever occurs first, and repetitively thereafter at or before reaching 200 hours TIS from the last inspection or replacement, do a detailed visual inspection of the left hand (LH) and right hand (RH) primary flight control rudder cables under the floor between FS 116.56 and FS 138.56, with specific focus on the cable and the pulley at FS126.06. Do the inspection as stated in paragraph 4. ACTION of M7 Aerospace SA226 Series Service Letter 226-SL-050, issued April 15, 2015, following the procedures specified in paragraph 2. ACCOMPLISHMENT INSTRUCTIONS, section B., subparagraph (2) of M7 Aerospace SA226 Series Service Bulletin 226-27-072, issued June 27, 2011.
Before further flight after any inspection required in paragraph (g) of this AD, if any one of the conditions described in paragraph 2. ACCOMPLISHMENT INSTRUCTIONS, section B., subparagraphs (3)(a) through (3)(d) of M7 Aerospace SA226 Series Service Bulletin 226-27-072, issued June 27, 2011, is found, replace the affected primary flight control rudder cable or cables with a new cable. Do the replacements following paragraph 2. ACCOMPLISHMENT INSTRUCTIONS, sections C. through E., including all subparagraphs of M7 Aerospace Service Bulletin 226-27-072, issued June 27, 2011.
Within the next 800 hours TIS after the last replacement or within the next 50 hours TIS after July 21, 2015 (the effective date of this AD), whichever occurs later, and repetitively thereafter every 800 hours TIS, replace the LH and RH primary flight control rudder cables with new cables. Do the replacements following paragraph 2. ACCOMPLISHMENT INSTRUCTIONS, sections C. through E., including all subparagraphs of M7 Aerospace SA226 Series Service Bulletin 226-27-072, issued June 27, 2011.
(1) For cables with more than 6,000 hours TIS: Inspect cables for deficiencies within 10 hours TIS after September 1, 2011, (the effective date retained from AD 2011-17-07).
(2) If any deficiencies are found during the inspection required in paragraph (j)(1) of this AD, before further flight replace the cable(s).
(3) Replace all other primary control and trim tab cables (pilot and co-pilot aileron cables, rudder/aileron interconnect cables, aileron trim tab cables, rudder trim tab cables, and elevator cables) within the initial compliance times as listed in paragraphs (j)(3)(i) through (j)(3)(iii) below and repetitively thereafter at intervals not to exceed 3,500 hours TIS. Do the replacements following paragraph 2. ACCOMPLISHMENT INSTRUCTIONS, sections C. through E., including all subparagraphs of M7 Aerospace SA226 Series Service Bulletin 226-27-072, issued June 27, 2011.
(i) For cables with less than or equal to 3,500 hours TIS: replace cables when the control cables reach a total of 3,500 hours TIS or 150 hours TIS after September 1, 2011, (the effective date retained from AD 2011-17-07), whichever occurs later.
(ii) For cables with less than or equal to 5,000 hours TIS but greater than 3,500 hours TIS: replace cables within 150 hours TIS after September 1, 2011, (the effective date retained from AD 2011-17-07).
(iii) For cables with more than 5,000 hours TIS: replace cables within 50 hours TIS after September 1, 2011, (the effective date retained from AD 2011-17-07).
Between 50 hours TIS and 200 hours TIS after installing any new control cable as required in paragraphs (g) through (j) of this AD, including all subparagraphs, check (set) flight control cable tension following paragraph 2. ACCOMPLISHMENT INSTRUCTIONS, sections C. through E. of M7 Aerospace SA226 Series Service Bulletin 226-27-072, issued June 27, 2011.
