We are superseding an airworthiness directive (AD) 2007-06-06 for B-N Group Ltd. Models BN-2, BN-2A, BN-2A-2, BN-2A-3, BN-2A-6, BN- 2A-8, BN-2A-9, BN-2A-20, BN-2A-21, BN-2A-26, BN-2A-27, BN-2B-20, BN-2B- 21, BN-2B-26, BN-2B-27, BN2A MK. III, BN2A MK. III-2, BN2A MK. III-3 BN2A, BN2B, and BN2A MKIII (all models on TCDS A17EU and A29EU) 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 in the inner shell of certain pitot/static pressure heads. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions in paragraphs (f)(1) through (f)(4) of this AD:
(1) For airplanes equipped with pitot/static pressure head part number (P/N) DU130-24: Within 50 hours time-in-service (TIS) after April 19, 2016 (the effective date of this AD) and repetitively thereafter at intervals not to exceed 50 hours TIS, inspect the pitot/static pressure head for cracks and/or separation and perform a leak test following the procedures in the action section of Britten-Norman Service Bulletin SB 310, Issue 4, dated September 25, 2015.
(2) For airplanes equipped with pitot/static pressure head part number (P/N) DU130-24: If, during an inspection or test required in paragraph (f)(1) of this AD discrepancies are found, before further flight, replace the pitot/static pressure head with an airworthy part.
(3) For airplanes equipped with pitot/static pressure head part number (P/N) DU130-24: Corrections performed on airplanes as required in paragraph (f)(2) of this AD do not constitute terminating action for the repetitive actions required in paragraph (f)(1) of this AD.
(4) For airplanes not equipped with a pitot/static pressure head P/N DU130-24 on the effective date of this AD: After April 19, 2016 (the effective date of this AD), do not install a pitot/static pressure head P/N DU130-24.
