AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule; correction.

SUMMARY:

This document corrects an error that appeared in airworthiness directive (AD) 2002-16-22 that was published in the Federal Register on August 15, 2002 (67 FR 53434). The error resulted in an incorrect reference to a supplemental type certificate. This AD is applicable to certain Boeing Model 727 series airplanes that have been converted from a passenger- to a cargo-carrying (“freighter”) configuration. This AD requires, among other actions, installation of a fail-safe hinge, redesigned main deck cargo door warning and power control systems, and 9g crash barrier.

DATES:

Effective September 19, 2002.

SUPPLEMENTARY INFORMATION:

Airworthiness Directive (AD) 2002-16-22, amendment 39-12861, applicable to certain Boeing Model 727 series airplanes that have been converted from a passenger- to a cargo-carrying (“freighter”) configuration, was published in the Federal Register on August 15, 2002 (67 FR 53434). That AD requires, among other actions, installation of a fail-safe hinge, redesigned main deck cargo door warning and power control systems, and 9g crash barrier.

As published, Note 5 of AD 2002-16-22 states, “Installation of National Aircraft Service, Inc. (NASI), Vent Door System STC ST01438CH, is an acceptable means of compliance with the requirements of paragraph (e) of this AD.” However, the correct supplemental type certificate (STC) is ST01270CH, as discussed in paragraph 13 of “Main Deck Cargo Door Systems” in the preamble of the final rule. Paragraph 13 also contains an error in that it refers to “Pemco ST01270CH” rather than “NASI ST01270CH.”

Since no other part of the regulatory information has been changed, the final rule is not being republished in the Federal Register

The effective date of this AD remains September 19, 2002.
