trademark in accordance with the Accomplishment Instructions of Raytheon Mandatory Service Bulletin SB 57-3328 Issued July 1999.

 

2. Replace any lower forward wing bolt that has the “Mercury Aerospace” trademark with an FAA-approved bolt, and replace the associated nuts and washers; in accordance with SB 57-3328.

 

Note: FAA AD 2001-02-10 Amdt 39-12094 refers.
