Airworthiness Directive · Amendment 39-17735 · Landing gear
Costruzioni Aeronautiche Tecnam srl Airplanes
This AD applies to Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes, serial numbers (S/N) 001/US through S/N 9999/US, certificated in any category.
We are adopting a new airworthiness directive (AD) for Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks of the nose landing gear (NLG) lower link. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions as specified in paragraphs (f)(1) through (f)(5) of this AD:
(1) For airplanes with an NLG lower link assembly part number (P/N) 26-8-1417-000 installed, within the next 25 hours time-in-service (TIS) after March 14, 2014 (the effective date of this AD) or within the next 30 days after March 14, 2014 (the effective date of this AD), whichever occurs first, do a detailed inspection of the NLG lower link P/N 26-8-1417-1 (this is in the NLG-000 assembly) following Costruzioni Aeronautiche Tecnam Service Bulletin No. SB 128-CS, Revision 0, dated May 15, 2013.
(2) If a crack is detected during the inspection required by paragraph (f)(1) of this AD, before further flight, replace the NLG lower link assembly with an improved assembly. Follow the instructions in Costruzioni Aeronautiche Tecnam Job Card 442, P2006T NLG upper link replacement, Revision 1, dated February 11, 2013; Costruzioni Aeronautiche Tecnam Job Card 468, New NLG Spring replacement, dated October 12, 2012; or Costruzioni Aeronautiche Tecnam Job Card 528, P2006T NLG retraction spring installation, Revision 1, dated April 2, 2013, as applicable, as specified in Costruzioni Aeronautiche Tecnam Service Bulletin No. SB 128-CS, Revision 0, dated May 15, 2013.
Note 1 to paragraphs (f)(2) and (f)(3) of this AD: Although Costruzioni Aeronautiche Tecnam Job Card 442, Revision 1, dated February 11, 2013, is designated P2006T NLG upper link replacement, it still pertains to the replacement of the lower link.
(3) Unless already done as required by paragraph (f)(2) of this AD, within the next 50 hours TIS after March 14, 2014 (the effective date of this AD) or within the next 60 days after March 14, 2014 (the effective date of this AD), whichever occurs first, replace the NLG lower link assembly P/N 26-8-1417-000 with an improved assembly. Follow the instructions in Costruzioni Aeronautiche Tecnam Job Card 442, P2006T NLG upper link replacement, Revision 1, dated February 11, 2013; Costruzioni Aeronautiche Tecnam Job Card 468, New NLG Spring replacement, dated October 12, 2012; or Costruzioni Aeronautiche Tecnam Job Card 528, P2006T NLG retraction spring installation, Revision 1, dated April 2, 2013, as applicable, as specified in the Costruzioni Aeronautiche Tecnam Service Bulletin No. SB 128-CS, Revision 0, dated May 15, 2013.
(4) After replacement of the NLG lower link assembly as required by paragraph (f)(2) or (f)(3) of this AD, as applicable, do not install an NLG lower link assembly P/N 26-8-1417-000 or an NLG lower link part P/N 26-8-1417-1 (this is in the NLG-000 assembly) on that airplane.
(5) For an airplane with an NLG lower link assembly P/N 26-8-8000-000 already installed, after the effective date of this AD, do not install an NLG lower link assembly P/N 26-8-1417-000 or a NLG lower link P/N 26-8-1417-1 on that airplane.
This AD provides credit for the inspection required in paragraph (f)(1) of this AD and any necessary replacement required in paragraphs (f)(2) or (f)(3) of this AD if already done before March 14, 2014 (the effective date of this AD) following Costruzioni Aeronautiche Tecnam Service Bulletin No. SB 104-CS, Edition 2, Revision 1, dated March 28, 2013.
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.
