PACIFIC AEROSPACE LIMITED: Amendment 39-21213; Docket No. FAA-2020-0769; Product Identifier 2018-CE-033-AD. |
(a) EFFECTIVE DATE This AD becomes effective September 14, 2020. (b) AFFECTED ADS None. (c) APPLICABILITY This AD applies to Pacific Aerospace Limited Model 750XL airplanes, certificated in any category, with a wing lightning protection panel installed. (d) SUBJECT Air Transport Association of America (ATA) Code 39: Electrical Wiring. (e) REASON This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as insufficient electrical bonding of the wing lightning protection panels. The FAA is issuing this AD to detect and correct insufficient electrical bonding between the wing lightning protection panels and the airframe that, in the event of a lightning strike in that area, could result in an inflight fire. (f) COMPLIANCE Comply with the actions listed in paragraphs (g) and (h) of this AD within the compliance times specified, unless already done. (g) FOR AIRPLANES WITH SHORT RANGE WINGS For airplanes approved for operation under instrument flight rules (IFR) do the following actions within 30 days after September 14, 2020 (the effective date of this AD), and for airplanes not approved for operation under IFR, do the following actions within 60 days after September 14, 2020 (the effective date of this AD): (1) Inspect each wing upper surface by following paragraphs 2.A.(1) through 2.A.(3) of the Accomplishment Instructions-Short Range Wing in Pacific Aerospace Service Bulletin PACSB/XL/092, Issue 2, dated December 15, 2017 (PACSB/XL/092, Issue 2). (i) Using a mill-ohmmeter, determine the resistance between the test point on each panel and the fuel cap. (ii) If the resistance is greater than 100 milliohms, before further flight, repair the upper surface electrical bonding by following paragraph 2.B. of the Accomplishment Instructions - Short Range Wing in PACSB/XL/092, Issue 2. (2) Inspect each wing lower surface by following paragraphs 2.C.(1) through 2.C.(3) of the Accomplishment Instructions - Short Range Wing in PACSB/XL/092, Issue 2. (i) Using a mill-ohmmeter, determine the resistance between each test point and the airframe. (ii) If the resistance is greater than 100 milliohms, before further flight, repair the lower surface electrical bonding by following paragraph 2.D. of the Accomplishment Instructions - Short Range Wing in PACSB/XL/092, Issue 2. (h) FOR AIRPLANES WITH EXTENDED RANGE WINGS For airplanes approved for operation under IFR, do the following actions within 30 days after September 14, 2020 (the effective date of this AD), and for airplanes not approved for operation under IFR, do the following actions within 60 days after September 14, 2020 (the effective date of this AD): (1) Inspect each wing upper surface by following paragraphs 3.A.(1) through 3.A.(3) of the Accomplishment Instructions - Extended Range Wing in PACSB/XL/092, Issue 2. (i) Using a mill-ohmmeter, determine the resistance between the test point on each panel and the fuel cap. (ii) If the resistance is greater than 100 milliohms, before further flight, repair the upper surface electrical bonding by following paragraph 3.B. of the Accomplishment Instructions - Extended Range Wing in PACSB/XL/092, Issue 2. (2) Inspect each wing lower surface by following paragraphs 3.C.(1) through 3.C.(3) of the Accomplishment Instructions - Extended Range Wing in PACSB/XL/092, Issue 2. (i) Using a mill-ohmmeter, determine the resistance between each test point and the airframe. (ii) If the resistance is greater than 100 milliohms, before further flight, repair the lower surface electrical bonding by following paragraph 3.D. of the Accomplishment Instructions - Extended Range Wing in PACSB/XL/092, Issue 2.
