This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas airplanes, that requires reversing the ground stud installation of the main battery, and installing a new nameplate on the cover of the battery. This action is necessary to prevent damage to equipment or possible fire in the electrical/electronics equipment compartment due to electrical arcing between the ground stud of the main battery and adjacent structure. This action is intended to address the identified unsafe condition.
To prevent damage to equipment or possible fire in the electrical/electronics equipment compartment due to electrical arcing between the ground stud of the main battery and adjacent structure; accomplish the following:
(a) Within 1 year after the effective date of this AD, reverse the installation of the ground stud for the main battery and install a new nameplate on the cover of the battery; in accordance with McDonnell Douglas Alert Service Bulletin MD80-24A159, Revision 01, dated January 24, 2000.
(b) Accomplishment of the actions specified in paragraph (a) of this AD before the effective date of this AD, in accordance with McDonnell Douglas Service Bulletin MD80-24A159, dated March 15, 1996, is considered to be an acceptable method of compliance with paragraph (a) of this AD.
(c) In accordance with 14 CFR 39.19, the Manager, Los Angeles Aircraft Certification Office, FAA, is authorized to approve alternative methods of compliance for this AD.
