Background

    The proposed interim policy memorandum provides Federal Aviation 
Administration (FAA) certification policy on the compliance issues 
associated with high altitude flight. This memo provides applicants 
with information on how the FAA will evaluate petitions for exemption 
from Sec.  25.841(a), as amended by Amendment 25-87. For airplanes with 
wing-mounted engines, this regulation in effect limits the maximum 
operating altitude of airplanes approved to this standard to 40,000 
feet. Several airframe manufacturers have asked the FAA to develop a 
new safety standard, which is being addressed in rulemaking activities. 
Those manufacturers have also asked for interim policy to provide 
relief because high altitude flight offers benefits to airplane 
performance in terms of reduced drag and lower fuel burn.

    Issued in Renton, Washington, on May 15, 2003.

Acting Manager, Transport Airplane Directorate Aircraft Certification 
Service.
