First, understand that all ADs are formatted exactly the same way.
Starting at the top of the AD you see the AD number 87-03-06 R1.
The 87 is the year the AD was issued, 1987. 03 stands for the 3rd bi-weekly issue of 1987. The 06 stands for the 6th AD in sequence issued in the 3rd bi-weekly. R1 indicates that this is the 1st revision to the AD.
Then you find the Effective Date of the AD. In this case it’s March 12, 1987.
Then comes the actual FAR 39 Amendment number to the FAR. In this case it’s Amendment 39-5513, which was the original AD, as amended by 39-5557, which is revision 1.
Each amendment to FAR 39 is an actual revision to the statute.
Then comes the applicability statement. It defines the product to which the AD applies, and usually includes specific serial numbers and other identification information. This is also where you find the Category of certification information such as Standard, Restricted, Experimental, and the like. If it refers to a product in ALL categories, then all categories of certification are included.
Then comes a Compliance statement. Next, there is a statement as to why the AD was issued. Following is the body of the AD including any inspections involved, repairs or alterations involved. Then comes a statement, if it requires a recurring inspection, as to how recurring inspections may be discontinued. Then a statement as to whether or not the aircraft can be ferried? Possibly a statement next as to adjusting inspection intervals. Then the possibility of suggesting and having an approval for some other way of complying with the AD. And finally a statement describing who issued the AD along with there name, address, phone, and the like if you want to contact the issuing FAA office. This AD is complex in that it requires some out-of-the-ordinary procedures. It uses the expression “whichever comes later” with respect to Time-in-Service. It also requires a mandatory replacement of bolts in place of rivets at a specified time. This will be a Major Alteration when that occurs requiring a FAA Form 337 because the replacement of the rivets with bolts is a major change in type design. It is also a major change to a primary flight control. The AD however, is always FAA approved design data so any additional data approval is not required. However, if a mechanic wanted to use Hilok bolts instead of the regular bolts mentioned in the referenced Beech Service Bulletin, an FAA approval as an alternate method could be approved. Always remember, the AD and any data referenced in an AD are always considered FAA approved. Be sure you use only the revision of referenced data cited in the AD.
