2022-11-19: Aircraft Fuel System, Engine Oil System (Airframe)

1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2022-11-19 Bell Textron Inc.: Amendment 39-22069; Docket No. FAA-2022-0387; Project Identifier AD-2021-01225-R. (a) Effective Date This airworthiness directive (AD) is effective July 6, 2022. (b) Affected ADs None. (c) Applicability This AD applies to Bell Textron Inc. Model 212, 412, 412CF, and 412EP helicopters, certificated in any category, with an engine oil check valve part number (P/N) 209-062-520-001 or fuel check valve P/N 209-062-607-001 manufactured by Circor Aerospace that: (1) Is marked "Circle Seal" and "CORONA CA," except not a check valve marked with "TQL," and (2) Has a manufacturing date code of, or prior to, "9/11" (September 2011), or does not have a manufacturing date code, installed. (d) Subject Joint Aircraft System Component (JASC) Code: 2800 Aircraft Fuel System and 7900 Engine Oil System (Airframe). (e) Unsafe Condition This AD was prompted by a report of a cracked check valve. The FAA is issuing this AD to detect a cracked check valve. The unsafe condition, if not addressed, could result in loss of lubrication or fuel to the engine, failure of the engine or a fire, and subsequent loss of control of the helicopter. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions (1) Within 25 hours time-in-service (TIS) or 30 days, whichever occurs first after the effective date of this AD, using a caliper or equivalent, measure the outside diameter (O.D.) of the check valve housing at the center, and the O.D. of the check valve housing at the inlet end where the threaded fitting is installed. If the dimension measured at the inlet end is greater than 0.003 inch (0.0762 mm) compared to the measurement at the center, do the following: (i) Before further flight, and thereafter at intervals not to exceed 25 hours TIS or 30 days, whichever occurs first, using a flashlight, visually inspect the check valve for a crack and leak, paying particular attention to the area at the inlet end where the threaded fitting is installed. If there is a crack or leak, before further flight, remove the check valve from service. Removing the check valve from service terminates the repetitive inspections required by this AD for that check valve. (ii) Within 600 hours TIS or 12 months, whichever occurs first, remove the check valve from service. Removing the check valve from service terminates the repetitive inspections required by this AD for that check valve. (2) As of the effective date of this AD, do not install an engine oil or fuel check valve identified in paragraph (c) of this AD on any helicopter. (h) Alternative Methods of Compliance (AMOCs) (1) The Manager, DSCO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the certification office, send it to the attention of the person identified in paragraph (i) of this AD. Information may be emailed to: [email protected]. (2) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office.
