Airworthiness Directive · Amendment 39-16090 · Vulcanair S.p.A. Models P 68, P 68B, P 68C, P 68C-TC, and P 68 “OBSERVER” Airplanes
Vulcanair S.p.A. Models P 68, P 68B, P 68C, P 68C-TC, and P 68 “OBSERVER” Airplanes
This AD applies to Models P 68, P 68B, P 68C, P 68C-TC, and P 68 “OBSERVER” airplanes, serial numbers 001 through 356, that are certificated in any category.
We are adopting a new airworthiness directive (AD) to supersede AD 85-08-04, which applies to certain Vulcanair S.p.A. Models P 68, P 68B, P 68C, P 68C-TC, and P 68 "OBSERVER" airplanes. AD 85- 08-04 currently requires you to repetitively visually inspect the front and rear wing spars for cracks. If cracks are found, AD 85-08-04 requires you to modify the wing spars. The wing spar modification terminates the repetitive inspection AD action and may be installed before cracks develop. Since we issued AD 85-08-04, the manufacturer revised the modification kit and identified additional airplane serial numbers that require the inspection and/or modification. Consequently, this AD would retain the actions of AD 85-08-04, allow you to install the revised modification kit, and add additional serial numbers to the Applicability section. We are issuing this AD to detect and correct cracks in the front and rear wing spar, which could result in the wing separating from the airplane. This failure could lead to loss of control.
For airplane serial numbers 001 through 328, to address this problem, you must do the following, unless already done:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Visually inspect the front and rear wing spars for cracks | Initially inspect within the next 100 hours time-in-service (TIS) after May 17, 1985 (the effective date of AD 85-08-04), or upon reaching 2,100 hours total TIS, whichever occurs later. Repetitively inspect thereafter at intervals not to exceed 500 hours TIS | Follow Partenavia Costruzioni Aeronautiche S.p.A Service Bulletin No. 65 Rev. 3, dated September 30, 1985; or Partenavia Costruzioni Aeronautiche S.p.A Service Bulletin No. 65 Rev. 1, dated September 27, 1984. |
| (2) Repair all cracks found and modify the front and rear wing spars | Before further flight after any inspection specified in paragraph (e)(1) of this AD where cracks are found. Modification of the front and rear wing spar terminates the repetitive inspection requirements of this AD | Follow Partenavia Costruzioni Aeronautiche S.p.A Service Bulletin No. 65 Rev. 3, dated September 30, 1985; or Partenavia Costruzioni Aeronautiche S.p.A Service Bulletin No. 65 Rev. 1, dated September 27, 1984. |
| (3) To terminate the repetitive inspection requirements of this AD, you may modify the front and rear wing spar | Before further flight after any inspection specified in paragraph (e)(1) of this AD where cracks are not found | Follow Partenavia Costruzioni Aeronautiche S.p.A Service Bulletin No. 65 Rev. 3, dated September 30, 1985; or Partenavia Costruzioni Aeronautiche S.p.A Service Bulletin No. 65 Rev. 1, dated September 27, 1984. |
(f) For airplane serial numbers 329 through 356, to address this problem, you must do the following, unless already done:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Visually inspect the front and rear wing spars for cracks | Initially within the next 100 hours TIS after January 4, 2010 (the effective date of this AD), or upon reaching 2,100 total hours TIS, whichever occurs later. Repetitively inspect thereafter at intervals not to exceed 500 hours TIS | Follow Partenavia Costruzioni Aeronautiche S.p.A Service Bulletin No. 65 Rev. 3, dated September 30, 1985. |
| (2) Repair all cracks found and modify the front and rear wing spars | Before further flight after any inspection specified in paragraph (f)(1) of this AD where cracks are found. Modification of the front and rear wing spar terminates the repetitive inspection requirements of this AD | Follow Partenavia Costruzioni Aeronautiche S.p.A Service Bulletin No. 65 Rev. 3, dated September 30, 1985. |
| (3) To terminate the repetitive inspection requirements of this AD, you may modify the front and rear wing spar | Before further flight after any inspection specified in paragraph (e)(1) of this AD where cracks are not found | Follow Partenavia Costruzioni Aeronautiche S.p.A Service Bulletin No. 65 Rev. 3, dated September 30, 1985. |
