We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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:
Unless already done, do the following.
(1) For Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 series airplanes, serial numbers 003 through 561 inclusive: Do the actions required by paragraph (f)(1)(i) or (f)(1)(ii) of this AD, as applicable, in accordance with paragraph 3.B., Part A, of Bombardier Service Bulletin 8-27-107, dated October 16, 2007.
(i) For airplanes on which fuselage spoiler cable disconnect sensing device, Modsum 8Q100898, has been installed as of the effective date of this AD: Within 1,000 flight hours after the effective date of this AD, inspect the fuselage spoiler cable disconnect sensing device for correct assembly.
(ii) For airplanes on which fuselage spoiler cable disconnect sensing device, Modsum 8Q100898, has not been installed as of the effective date of this AD: Concurrently with the installation of Modsum 8Q100898, inspect the fuselage spoiler cable disconnect sensing device for correct assembly.
Note 1: AD 2007-21-16, amendment 39-15234, requires the installation of Modsum 8Q100898.
(2) For Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 series airplanes, serial numbers 562 through 644 inclusive: Within 1,000 flight hours after the effective date of this AD, inspect the fuselage spoiler cable disconnect sensing device for correct assembly in accordance with paragraph 3.B., Part A, of Bombardier Service Bulletin 8-27-107, dated October 16, 2007.
Note 2: The fuselage spoiler cable disconnect sensing device was installed in production on the airplanes identified in paragraph (f)(2) of this AD.
(3) For Bombardier Model DHC-8-400, -401, and -402 series airplanes, serial numbers 4003, 4004, 4006, and 4008 through 4164 inclusive: Within 1,000 flight hours after the effective date of this AD, inspect the fuselage spoiler cable disconnect sensing device for correct assembly in accordance with paragraph 3.B., Part A, of Bombardier Service Bulletin 84-27-34, dated October 3, 2007.
Note 3: The fuselage spoiler cable disconnect sensing device was installed in production on the airplanes identified in paragraph (f)(3) of this AD.
(4) For all airplanes: If an incorrectly assembled sensing device is detected during any inspection required by paragraph (f)(1), (f)(2), or (f)(3) of this AD, before further flight, inspect the components, replace worn or damaged components, and correctly re-assemble the sensing device. Do the actions in accordance with paragraph 3.B., Part B, of Bombardier Service Bulletin 8-27-107, dated October 16, 2007; or Bombardier Service Bulletin 84-27-34, dated October 3, 2007; as applicable.
