2019-07-02: Engine Oil Storage (Airframe Furnished)

Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): 2019-07-02 Robinson Helicopter Company: Amendment 39-19613; Docket No. FAA-2017-1236; Product Identifier 2017-SW-136-AD. (a) Applicability This AD applies to Robinson Helicopter Company Model R66 helicopters, serial numbers 0003 through 0789, 0791, 0794 and 0796, certificated in any category. (b) Unsafe Condition This AD defines the unsafe condition as broken baffle inside an oil tank. This condition could result in loss of oil pressure and oil flow to the engine, leading to engine failure and subsequent forced landing of the helicopter. (c) Effective Date This AD becomes effective May 17, 2019. (d) Compliance You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time. (e) Required Actions Within 100 hours time-in-service: (1) Visually inspect the oil tank outlet fitting color to determine if it is blue. If the fitting is blue, before further flight, replace the tank with an oil tank that does not have a blue fitting. (2) Locate the G689-1 oil tank assembly identification ink stamp on the top surface of the oil tank, and determine the revision letter. (i) If the identification ink stamp is followed by a revision letter F, G, H, or I unless previously installed, install a G805-1 angle as follows: [[Page 14847]] (A) Drain the engine oil and disconnect the F723-1 line assembly from the tank fitting at the firewall, using as reference Figure 1 of Robinson Helicopter Company R66 Service Bulletin SB-21A, Revision A, dated June 6, 2017. (B) Pinch the flanges of G805-1 angle at the minimum required to enable insertion, and insert the angle in the oil tank outlet fitting until the angle snaps in place. (C) Connect the F723-1 line assembly to the tank fitting. Special torque nut to 675 in.-lb. Torque stripe the fitting. (ii) If the identification ink stamp is followed by a revision letter J, determine if there is a yellow dot near the ink stamp. A yellow dot indicates that the angle has been pre-installed and that no further action is required by this AD. If there is not a yellow dot near the ink stamp, install a G805-1 angle by following the procedures in paragraphs (e)(2)(i)(A) through (e)(2)(i)(C) of this AD. (iii) If the identification ink stamp is followed by a revision letter K, no further action is required by this AD.
