Airworthiness Directive · Amendment 39-18586 · Power plant
Textron Aviation Inc. Airplanes
This AD applies to the Textron Aviation Inc. airplane models and serial numbers (type certificate previously held by Cessna Aircraft Company) that are certificated in any category listed in Table 1 to paragraph (c) of this AD. The new airplane affected by this AD is model number 175A, serial number 619, manufactured in 1960.
| Model | Serial Nos. | Year manufactured |
|---|---|---|
| (1) 175 | 55001 through 55703 | 1958. |
| (2) 175 | 55704 through 56238 | 1959. |
| (3) 175 | 28700A, 626, and 640 | 1958 and 1959. |
| (4) 175 A | 56239 through 56777 | 1960. |
| (5) 175 A | 619 | 1960. |
We are superseding Airworthiness Directive (AD) 2008-15-06 for certain Textron Aviation Inc. Models 175 and 175A airplanes (type certificate previously held by Cessna Aircraft Company). AD 2008-15-06 required checking the airplane logbook to determine if the original engine mounting brackets had been replaced. If the original engine mounting brackets were still installed, the AD required repetitively inspecting those brackets for cracks and replacing any cracked engine mounting bracket until all four original engine mounting brackets were replaced. Replacing all four original engine mounting brackets terminated the actions required in AD 2008-15-06. Since we issued AD 2008-15-06, we have determined that the applicability needs to be changed to add one serial number and remove another. This new AD retains the actions required in AD 2008-15-06 and changes the Applicability section. We are issuing this AD to correct the unsafe condition on these products.
(1) Check the airplane logbook to determine if all four of the original engine mounting brackets have been replaced. Do the logbook check at the following compliance time, as applicable. The owner/operator holding at least a private pilot certificate as authorized by section 43.7 may do this action.
(i) For airplanes previously affected by AD 2008-15-06: Within the next 30 days after September 2, 2008 (the effective date retained from AD 2008-15-06).
(ii) For the new airplane affected by this AD: Within the next 30 days after August 11, 2016 (the effective date of this AD).
(2) If you can positively determine that all four of the original engine mounting brackets have been replaced, no further action is required. Make an entry into the airplane logbook showing compliance with this portion of the AD in accordance with 14 CFR 43.9. The owner/operator holding at least a private pilot certificate as authorized by section 43.7 may do this action.
(3) If you cannot positively determine that all four of the original engine mounting brackets have been replaced, inspect each of the upper and lower engine mounting brackets on both the left and right sides for cracks following Cessna Single Engine Service Bulletin SEB07-2, Revision 2, dated June 18, 2007. Do the inspections at the following compliance times, as applicable.
(i) For airplanes previous affected by AD 2008-15-06: Initially inspect within the next 12 months after September 2, 2008 (the effective date retained from AD 2008-15-06). If no cracks are found, repetitively inspect thereafter at intervals not to exceed 500 hours time-in-service (TIS) until all four of the original engine mounting brackets are replaced.
(ii) For the new airplane affected by this AD: Initially inspect within the next 12 months after August 11, 2016 (the effective date of this AD). If no cracks are found, repetitively inspect thereafter at intervals not to exceed 500 hours TIS until all four of the original engine mounting brackets are replaced.
If cracks are found in any of the engine mounting brackets during any inspection required in paragraph (g)(3) of this AD, including all subparagraphs, before further flight after the inspection in which cracks are found, replace the cracked engine mounting bracket(s) following Cessna Single Engine Service Bulletin SEB07-2, Revision 2, dated June 18, 2007. Replacing the cracked engine mounting bracket terminates the repetitive inspections required in paragraphs (g)(3)(i) and (ii) of this AD only for the replaced engine mounting bracket.
To terminate the repetitive inspections required in paragraphs (g)(3)(i) and (ii) of this AD, you may replace all four original engine mounting brackets following Cessna Single Engine Service Bulletin SEB07-2, Revision 2, dated June 18, 2007.
For all airplanes affected by this AD: Before further flight after the engine mounting bracket is removed for replacement, dispose of every replaced bracket following 14 CFR 43.10, paragraph (c)(6), which states the following: “Mutilation. The part may be mutilated to deter its installation in a type certificated product. The mutilation must render the part beyond repair and incapable of being reworked to appear to be airworthy.”
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.
