FAA-18334)]


Minimum Altitudes for IFR Operations

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Technical amendment.

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

SUMMARY: The FAA is correcting the introductory text in paragraph (a) 
of Sec.  91.177 that was published on August 18, 1989. The phrase, ``or 
unless otherwise authorized by the Administrator'' was inadvertently 
removed from paragraph (a) introductory text. This action reinstates 
that phrase with a minor revision.

DATES: Effective June 2, 2010.

SUPPLEMENTARY INFORMATION:

Background

    On August 18, 1989 (54 FR 34288), the FAA published a final rule 
that revised 14 CFR part 91. In the final rule, the phrase in Sec.  
91.177 (a) introductory text ``unless otherwise authorized by the 
Administrator'' was inadvertently removed. The impact of this action 
was not apparent until the FAA recently amended the guidelines for 
establishing minimum vectoring altitudes. Without this phrase in the 
regulation, certain altitudes are unavailable to air traffic control. 
This action corrects this error with a minor revision. We are replacing 
the word ``Administrator'' with ``FAA''. The new phrase will read 
``unless otherwise authorized by the FAA''.

Good Cause for Immediate Adoption of This Final Rule

    Until recently, the FAA was unaware of the erroneous amendment to 
this regulation and its impact on minimum vectoring altitudes. The FAA 
concludes that immediate action is necessary to correct this error and 
therefore, finds that notice and public comment under 5 U.S.C. 553(b) 
are impracticable and contrary to the public interest. Further, the FAA 
finds that good cause exists under 5 U.S.C. 553(d) for making this rule 
effective immediately upon publication.

List of Subjects in 14 CFR Part 91

    Air traffic control, Aircraft, Airmen, Aviation safety, Reporting 
and recordkeeping requirements.
