That action would have required replacement of all clevis pins installed on the thrust reverser central drive units and upper and lower actuators, or replacement of pins that fail an on-wing rebound hardness test. Since we issued that NPRM, we determined there is no unsafe condition that warrants issuing an AD. The likelihood of this event occurring again and significantly damaging an aircraft is very low. Accordingly, we withdraw the proposed rule.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to add a new airworthiness directive (AD), applicable to (GE) CF6–80C2 and CF6– 80E1 series turbofan engines, was published in the Federal Register on February 25, 2008 (73 FR 9970). The proposed rule would have required replacement of all clevis pins installed VerDate Aug<31>2005 15:44 Oct 10, 2008 Jkt 217001 on the thrust reverser central drive units and upper and lower actuators, or replacement of pins that fail an on-wing rebound hardness test. That action results from failure of a thrust reverser during landing due to unapproved clevis pins being installed. The failure was due to lack of clevis pin hardness. The proposed actions were intended to prevent thrust reverser failure, which could lead to damage to the thrust reverser and airplane. Since we issued that NPRM we have determined we don’t need to issue an Airworthiness Directive to mandate an inspection. We have determined that the probability that inferior pin material is present in the fleet does not present sufficient risk to warrant an AD. However, operators and maintenance facilities should remain diligent in their normal maintenance practices to prevent installation of unapproved materials and to recognize when a clevis pin of inferior material is installed. We issued Safety Information Alert Bulletin No. NE–08–44, dated September 3, 2008, to aid in identifying and understanding the inferior clevis pin material. Upon further consideration, we determined there is no unsafe condition that warrants issuing an AD. The likelihood of this event occurring again and significantly damaging an aircraft is very low. Accordingly, we withdraw the proposed rule. Withdrawing this notice of proposed rulemaking constitutes only such action, and does not preclude us from issuing another notice in the future, nor does it commit us 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 and therefore, is not covered under Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979).

Airworthiness Directives; General Electric Company CF6-80C2 and 
CF6-80E1 Series Turbofan Engines

AGENCY: Federal Aviation Administration, DOT.

ACTION: Proposed rule; withdrawal.

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

SUMMARY: This action withdraws a notice of proposed rulemaking (NPRM) 
that proposed a new airworthiness directive (AD), applicable to General 
Electric Company (GE) CF6-80C2 and CF6-80E1 series turbofan engines. 
That action would have required replacement of all clevis pins 
installed on the thrust reverser central drive units and upper and 
lower actuators, or replacement of pins that fail an on-wing rebound 
hardness test. Since we issued that NPRM, we determined there is no 
unsafe condition that warrants issuing an AD. The likelihood of this 
event occurring again and significantly damaging an aircraft is very 
low. Accordingly, we withdraw the proposed rule.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to add a new airworthiness 
directive (AD), applicable to (GE) CF6-80C2 and CF6-80E1 series 
turbofan engines, was published in the Federal Register on February 25, 
2008 (73 FR 9970). The proposed rule would have required replacement of 
all clevis pins installed on the thrust reverser central drive units 
and upper and lower actuators, or replacement of pins that fail an on-
wing rebound hardness test. That action results from failure of a 
thrust reverser during landing due to unapproved clevis pins being 
installed. The failure was due to lack of clevis pin hardness. The 
proposed actions were intended to prevent thrust reverser failure, 
which could lead to damage to the thrust reverser and airplane.
    Since we issued that NPRM we have determined we don't need to issue 
an Airworthiness Directive to mandate an inspection. We have determined 
that the probability that inferior pin material is present in the fleet 
does not present sufficient risk to warrant an AD. However, operators 
and maintenance facilities should remain diligent in their normal 
maintenance practices to prevent installation of unapproved materials 
and to recognize when a clevis pin of inferior material is installed. 
We issued Safety Information Alert Bulletin No. NE-08-44, dated 
September 3, 2008, to aid in identifying and understanding the inferior 
clevis pin material.
    Upon further consideration, we determined there is no unsafe 
condition that warrants issuing an AD. The likelihood of this event 
occurring again and significantly damaging an aircraft is very low. 
Accordingly, we withdraw the proposed rule.
    Withdrawing this notice of proposed rulemaking constitutes only 
such action, and does not preclude us from issuing another notice in 
the future, nor does it commit us 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 and therefore, is not covered 
under Executive Order 12866, the Regulatory Flexibility Act, or DOT 
Regulatory Policies and Procedures (44 FR 11034, February 26, 1979).
