B PA-E23-250 27-7654001 and up Report 2049, Amendment 5

Need for the Correction The FAA has received reports that reference in the AD to two of the AFM reports contains incorrect information. In particular, reference to Report 1308, Revision B, contains the words "normally aspirated"; and reference to Report 1360, Revision B, contains the word "Turbocharged." Both of these reports apply to both normally aspirated and turbocharged airplanes.

Consequently, the FAA has determined that there is a need to clarify AD 83-22-01 to eliminate any confusion concerning the particular report that the owners/operators of the affected airplanes need to incorporate into their AFM.

Correction of Publication This document clarifies the intent of AD 83-22-01 by eliminating reference to "normally aspirated" and "Turbocharged" in the applicable reports. This document also adds the amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13).

Since this action only clarifies the intent of AD 83-22-01, it has no adverse economic impact and imposes no additional burden on any person than would have been necessary by the existing AD. Therefore, the FAA has determined that prior notice and opportunity for public comment are unnecessary.
