The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) that would have applied to various normal and transport category rotorcraft with certain Honeywell enhanced ground proximity warning systems (EGPWS) installed. The NPRM was prompted by a software defect that prevents the EGPWS from providing terrain warnings. The NPRM would have required updating the software version of the EGPWS. Since issuance of the NPRM, the FAA has determined that the unsafe condition no longer exists and has confirmed that the majority of operators have updated their software as specified in the NPRM. Accordingly, the NPRM is withdrawn.
