Note to Inspectors
One of the least enjoyable tasks facing the aircraft inspector is the development of a decent AD list for an aircraft. The system is so complex, the requirements so varied, and the penalties for error or oversight severe. So most inspectors rely on stock lists provided by the FAA or the host of commercial data compilers and base their inspections on these. The problem is every aircraft is different and every stock AD list is too general to be used as supplied. That leaves the inspector with hours of really nasty paper work before the real inspection can begin.
First the inspector must read each of the AD's on the list to finally determine applicability. This can involve further reading of included service documents which often can contain thousands of serial numbers that must be investigated. Sometimes the service bulletin will have the numbers grouped under models and sometimes not. When they are grouped frequently there are several groups for the same model so you can never be quite sure you're finished. Then there are the appliance AD's. Virtually every list provider ignores these because they're difficult. So what is the inspector to do, read each of the 200 plus appliance AD's for possible applicability? If you want to do a good job that's exactly what you have to do.
It all adds up to about four to six hours of heavy duty research before the job of checking the airplane can begin. You can avoid this by ordering up an AD Search report from ADR. Use ADR exclusively for you inspection work and avoid the heavy fees of data providers who try, but just can't provide the intelligence needed for a really finished product. Pre-print your information on the report and give it to your customer. It will act as positive advertisement for the quality of your service.
