The FAA published a notice in the Federal Register on February 25, 2003 (68 FR 8794) to announce the availability of the proposed policy and invite interested parties to comment.


The FAA was asked to consider a 2-minute gas temperature overshoot limit approval within the 5-minute steady state gas temperature limit associated with the takeoff power or thrust rating established under § 33.7, for certain engine operating conditions. This policy provides additional guidance to establish a uniform approach for Aircraft Certification Offices (ACOs) to evaluate and approve up to a 2-minute gas temperature overshoot limit casued by thermal mismatch of engine hardware. This policy does not create any new requirements.
