Models named: DHC-2 Mk. I, DHC-2 Mk. II, DHC-2 Mk. III. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Viking Air Limited (type certificate previously held by Bombardier Inc. and de Havilland Inc.) Model DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III airplanes, all serial numbers, certificated in any category.
Compliance
For purposes of this AD, a “serviceable part” is a front fuselage strut that has a part number (P/N) other than P/N C2FS209 and C2FS210 and meets the conditions in either paragraph (f)(1) or (2) of this AD: (1) Has accumulated less than 15 years since first installation on an airplane; or (2) Has accumulated 15 or more years since first installation on an airplane and has been inspected in accordance with the requirements of this AD.
Required actions
Comply with the initial actions in paragraph (h) of this AD at the applicable compliance time in paragraph (g)(1), (2), or (3) of this AD, unless already done. (1) For airplanes with a front fuselage strut that has been installed for less than 15 years as of the effective date of this AD: Before each front fuselage strut accumulates 15 years since first installation on an airplane. (2) For airplanes with a front fuselage strut that has been installed for more than 15 years as of the effective date of this AD or with a front fuselage strut where the date of first installation on an airplane is unknown and the ultrasonic inspection required by paragraph (d)(2) of AD 2002-14-28 has not been done within the last 5 years: Before further flight. (3) For airplanes with a front fuselage strut that has been installed for more than 15 years as of the effective date of this AD or with a front fuselage strut where the date of first installation on an airplane is unknown and the ultrasonic inspection required by paragraph (d)(2) of AD 2002-14-28 has been done within the last 5 years: Within 5 years from the date of the last ultrasonic inspection done in accordance with paragraph (d)(2) of AD 2002-14-28.
Unsafe condition
This AD was prompted by 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 identifies the unsafe condition as the development of damage to the front fuselage struts and airframe lugs over time. The FAA is issuing this AD to address this condition. The unsafe condition, if not addressed, could result in failure of the front fuselage struts, which could lead to failure of the airframe and loss of airplane control.
Affected ADs
This AD replaces AD 2002-14-28, Amendment 39-12828 (67 FR 47684, July 22, 2002) (AD 2002-14-28).
