RRC Compressor Adaptor Couplings (h) Remove RRC compressor adaptor couplings, P/Ns 23039791-1, -2, and -3 from service next time the compressor rotor is disassembled for any reason, but not later than March 1, 2012. Installation Requirements for Compressor Adaptor Couplings (i) Machine the compressor impeller as follows: (1) Select and measure the pilot outside diameter (OD) of a new larger dash size coupling. (2) For example, if a -1 coupling was removed, a -2 coupling must be installed. (3) If a -3 coupling is removed, a new impeller is required. (4) Machine the inside diameter (ID) of the compressor impeller to achieve a fit of 0.0000 to 0.0013 inch. No fretting is allowed on the impeller after machining. (5) Due to previous fretting, an impeller with a -1 coupling removed might have to be machined for a -3 coupling. Plating of the impeller ID is not allowed. (6) Fluorescent penetrant inspect the impeller. (7) Install a new compressor adaptor coupling, P/N 23076559-2 or -3; or (8) If a new impeller is installed, then install compressor adaptor coupling, P/N 23076559-1. (9) Heating of the impeller per the engine overhaul manual is required to install the coupling to achieve the target fit specified in the following Table 3: TABLE 3.—IMPELLER-TO-COUPLING TARGET FIT New adaptor Adaptor OD Fit (interference) (i) 23076559–1 0.9000 to 0.9008 inch 0.0000 to –0.0013 inch. (ii) 23076559–2 0.9020 to 0.9028 inch 0.0000 to –0.0013 inch. (iii) 23076559–3 0.9040 to 0.9048 inch 0.0000 to –0.0013 inch. (10) The mating surfaces of the impeller and coupling must not have any fretting. Do not install a -1 coupling into a used impeller. Definition (j) For the purposes of this AD, next access is defined as when the compressor module is separated from the engine and disassembled for any reason. Alternative Methods of Compliance (k) The Manager, Los Angeles Aircraft Certification Office, has the authority to approve alternative methods of compliance for Alcor, EXTEX, and SAP adaptor couplings addressed in this AD if requested using the procedures found in 14 CFR 39.19.

Compliance: Required as indicated. To detect a crack in the blade and prevent loss of the blade and subsequent loss of control of the helicopter, accomplish the following: (a) Within 3 hours time-in-service (TIS) and at intervals not to exceed 3 hours TIS, clean and visually check both sides of each blade for a crack in the paint in the areas shown in Figure 1 of this AD.

(b) If a crack is found in the paint while complying with paragraph (a) of this AD, before further flight, inspect the blade by removing the blade and by abrading the area and following the other requirements in paragraph (c) of this AD. (c) Within the next 50 hours TIS, unless accomplished previously, and at intervals not to exceed 50 hours TIS, clean the blade by wiping down both surfaces of each blade in the inspection area depicted in Figure 1 of this AD using aliphatic naptha (C-305) or detergent (C-318) or equivalents. Using a 10X or higher power magnifying glass, visually inspect both sides of the blade in the areas depicted in Figure 1 of this AD. (1) If even a crack is found in the paint, before further flight, remove the blade. (2) Remove the paint to the bare metal in the area of the suspected crack by using Plastic Metal Blasting (PMB) or a nylon web abrasive pad. Abrade the blade surface in a span-wise direction only. Note 2: PMB may cause damage to helicopter parts if performed by untrained personnel. BHT-ALL-SPM, chapter 3, paragraph 3-24 pertains to the subject of this AD. (3) Using a 10X or higher power magnifying glass, inspect the blade for a crack. (i) If a crack is found, before further flight, replace the blade with an airworthy blade. (ii) If no crack is found in the blade surface, refinish the blade by applying one coat of MIL-P23377 or MIL-P-85582 Epoxy Polyamide Primer so that the primer overlaps the existing coats just beyond the abraded area. Let the area dry for 30 minutes to 1 hour. Then, apply one sealer coat of Polyurethane MILC85285 TYI CL2, color Number 27925 (semi-gloss white) per Fed. Std. 595. Reinstall the blade. Note 3: BHT-ALL-SPM, chapter 4, pertains to painting. (d) To request a different method of compliance or a different compliance time for this AD, follow the procedures in 14 CFR 39.19. Contact the Safety Management Group, FAA, for information about previously approved alternative methods of compliance. (e) Special flight permits may be issued by following 14 CFR 21.197 and 21.199 to operate the helicopter to a location where the requirements of this AD can be accomplished provided you do not find a crack in the paint during a check or inspection.

When Does This AD Become Effective? (a) This AD becomes effective on February 22, 2005. What Other ADs Are Affected by This Action? (b) This AD supersedes AD 74-06-01. What Airplanes Are Affected by This AD? (c) This AD affects Models PA-23-235, PA-23-250, and PA-E23-250 airplanes, all serial numbers, that are (1) certificated in any category; and (2) equipped with Garrett Aviation Services (Garrett) (formerly AiResearch) turbosuperchargers installed under supplemental type certificate (STC) SA852WE, SA909WE, or SA978WE; or installed under The New Piper, Inc. (Piper) Aircraft Drawing Number 32016. Note: Piper manufactured the majority of affected airplanes with the turbocharger system. The turbocharger system installed under Piper Aircraft Drawing Number 32016 (STC SA909WE) was a factory option on the Piper Model PA-23-250 or PA-E23-250 with serial numbers 27-2505 through 27-3943. What is the Unsafe Condition Presented in This AD? (d) This AD is the result of a report of a fatal accident related to the breakdown of the turbocharger oil reservoir following a fire in the engine nacelle. The actions specified in this AD are intended to prevent turbosupercharger oil reservoirs with inadequate fire resistance from failing when exposed to flame or exhaust gases. This failure could lead to an in-flight fire within the nacelle area penetrating the firewall and subsequent failure of the wing spar. What Must I do to Address This Problem? (e) To address this problem, you must do the following:
