Federal Register Volume 80, Issue 118 (June 19, 2015)

The FAA is withdrawing a notice of proposed rulemaking (NPRM). The NPRM proposed a new airworthiness directive (AD) that had applied to AlliedSignal oil scavenge pumps, part numbers (P/Ns) 101633-01 and - 02 and Rajay Inc. oil scavenge pumps, P/Ns 1025-1 and -2 installed on Continental Motors, Inc. (CMI) IO-470 and TSIO-520 reciprocating engines and on Lycoming Engines, Inc., (Lycoming) IO-360, IO-540, and O-360 reciprocating engines. We have found no service difficulties with these model oil scavenge pumps when installed on the affected engines. Accordingly, we withdraw the proposed rule.

Airworthiness Directives; AlliedSignal Inc. and Rajay Inc. Oil 
Scavenge Pumps

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Proposed rule; withdrawal.

-----------------------------------------------------------------------

SUMMARY: The FAA is withdrawing a notice of proposed rulemaking (NPRM). 
The NPRM proposed a new airworthiness directive (AD) that had applied 
to AlliedSignal oil scavenge pumps, part numbers (P/Ns) 101633-01 and -
02 and Rajay Inc. oil scavenge pumps, P/Ns 1025-1 and -2 installed on 
Continental Motors, Inc. (CMI) IO-470 and TSIO-520 reciprocating 
engines and on Lycoming Engines, Inc., (Lycoming) IO-360, IO-540, and 
O-360 reciprocating engines. We have found no service difficulties with 
these model oil scavenge pumps when installed on the affected engines. 
Accordingly, we withdraw the proposed rule.

DATES: As of June 19, 2015, the proposed rule published February 20, 
1997 at 62 FR 7730 is withdrawn.

FOR FURTHER INFORMATION CONTACT: Richard McCauley, Aerospace Engineer, 
Seattle Aircraft Certification Office, FAA, Transport Directorate, 1601 
Lind Avenue SW., Renton, WA 98055-4056; phone: 425-917-6502; fax: 425-
917-6590; email: [email protected].

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with a proposed AD (62 FR 7730, February 20, 1997). The proposed AD had 
applied to AlliedSignal oil scavenge pumps, P/Ns 101633-01 and -02 and 
Rajay Inc. oil scavenge pumps, P/Ns 1025-1 and -2 installed on CMI IO-
470 and TSIO-520 reciprocating engines and on Lycoming IO-360, IO-540, 
and O-360 reciprocating engines. The NPRM proposed to require initial 
and repetitive inspections of the oil scavenge pump for the security of 
the snap ring installation, snap ring and washer wear, and shaft groove 
wear, and their replacement, if necessary, with serviceable parts. The 
proposed action was prompted by reports of severe wear on the end plate 
of the oil scavenge pump. The proposed actions were intended to prevent 
oil scavenge pump snap ring failure causing severe wear on the pump end 
plate, which could result in loss of engine oil and subsequent engine 
shutdown.
    Since we issued the NPRM (62 FR 7730, February 20, 1997), 
additional information became available after the public comment period 
closed on April 21, 1997.
    Upon further consideration, we hereby withdraw the proposed rule 
for the following reason:
     We reviewed service difficulty reports, AD databases, and 
airplane manufacturer's data and found no unsafe condition in the last 
19 years of service history associated with these oil scavenge pumps 
installed on the affected engines.
    Withdrawal of the NPRM (62 FR 7730, February 20, 1997) constitutes 
only such action, and does not preclude the agency from issuing another 
notice in the future, nor does it commit the agency to any course of 
action in the future.
    Since this action only withdraws a notice of proposed rulemaking, 
it is neither a proposed nor a final rule. Therefore, Executive Order 
12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979) do not cover this 
withdrawal.

    Issued in Burlington, Massachusetts, on June 10, 2015.
