M7 Aerospace LP Airplanes
Superseded. A later AD replaced this one: AD 2015-13-10. Comply with the one in force.
This AD applies to the following M7 Aerospace LP airplanes, certificated in any category, as identified in Table 1 of this AD:
| Model— | Serial Nos.— |
|---|---|
| SA226-T | T265, T267. |
| SA226-T(B) | T(B)348. |
| SA226-TC | TC277. |
| SA226-AT | AT071, AT072, AT073. |
We are adopting a new airworthiness directive (AD) for certain M7 Aerospace LP Models SA226-T, SA226-T(B), SA226-TC, and SA226-AT airplanes. This AD requires 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 was prompted by a report of a failure of a rudder control cable. We are issuing this AD to correct the unsafe condition on these products.
(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 of this AD).
(2) If any deficiencies are found during the inspection required in paragraph (g)(1) of this AD, before further flight replace cables.
(1) Replace primary control cables within the initial compliance times as listed below and repetitively thereafter at intervals not to exceed 3,500 hours time-in-service (TIS):
(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 of this AD), 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 of this AD).
(iii) For cables with more than 5,000 hours TIS: Replace cables within 50 hours TIS after September 1, 2011 (the effective date of this AD).
(2) Between 50 hours TIS and 200 hours TIS after installing any new control cable as required in paragraphs (g)(2) or (h)(1) of this AD, check (set) flight control cable tension.
