Rapid AD Search - Serial Number based reports by Email on small aircraft & helicopters

Designed primarily for the aircraft owner/operator or the small volume maintenance facility, ADR will conduct single aircraft AD applicability searches via the Internet. You submit aircraft specific data (Make, Model, Serial Numbers, etc.) by completing an online form (Order Input Form) and ADR will generate, within 24 to 48 hours, a comprehensive survey of AD applicability on any small aircraft or rotorcraft. The following reports and documents are generated or furnished in the Adobe™ Acrobat™ PDF format report and transmitted to you by E-Mail:

1. Applicable or Possibly Applicable ADs: List including any conditions affecting applicability. These include airframe, engine, propeller and appliance ADs.
2. Not Applicable (Close, but no cigar): AD List. Includes N/A by S/N, N/A by unperformed STC, N/A by service bulletin, AD older than type certificate, wrong engine type, wrong propeller type, superseded and others.
3. Service Documents: A listing of service documents referenced in the applicable or possibly applicable ADs.
4. Summary of Recurring Requirements: Tabulates all recurring requirements of applicable or possibly applicable ADs including any terminating or converting actions that terminate or change recurring classification..
5. NPRMs: Listing of any proposed ADs that would affect the aircraft if and when issued.
6. New ADs: A listing of ADs revised or newly issued within the past 12 months.
7. Historic ADs: A listing of appliance ADs considered to have been outmoded by time or usage and therefore excluded from the above reports.
8. Index to ADs: A listing in numerical order of all the ADs shown in the combined reports referencing the section number.
9. Work/Sign-off sheets: Including all ADs identified in 1. above.
10. Recurring sign-off sheet: For each recurring AD with space for 7 additional sign-offs. (Print on both sides of paper to double recurring signoff capacity.)
11. N/A Signoff sheet:  A place to indicate ADs checked and found not applicable to this aircraft - includes blanks for additional AD's determined to be N/A. (There is no regulatory requirement to "sign-off" N/A AD's, but inspectors feel better doing it this way.)
12. Superseded Sheet: A listing on one page of all ADs against this aircraft that have been superseded.
13. Copies of recurring ADs and any ADs issued or modified within the past 12 to 14 months: Helpful in annual inspection reviews.
14. Copies of all proposed ADs (NPRM's): That appear likely to apply to the aircraft being searched.
15. Copies of the current type certificate Data Sheets: For the aircraft being searched.  (Airframe, engine and propeller.)

The search process reviews airframe, engine, propeller, carburetor and magnetos by serial number against the AD and service bulletin database.  Appliance ADs are categorized by aircraft type so you won't find oxygen system ADs on a helicopter or prop governor or fabric related AD's on a Cessna 150.  Also checked are combination ADs where applicability is determined by matching airframe to engine or engine to prop combinations.  There are even some ADs that apply by matching airframe to magneto!  Also checked are those AD's that apply strictly by N number such as those incidents arising from bad fuel a few years ago.

The AD Search program functions by submitting the aircraft profile through a database containing all the serial numbers in the ADs and applicable service bulletins. (About 40,000 in all). Along the way it tests thousands of combinations and possibilities FOR THIS SINGLE AIRCRAFT yielding a comprehensive and individual aircraft specific listing of ADs. Search depth examples  No other system in the world even comes close to the speed and accuracy of AD Search.

Other search systems that search only by model are severely deficient.  Explanation. 
Many, if not most, ADs apply to specific serial number ranges, or to other criteria that is single airframe specific.  A Search by model only, or worse yet, series, results in a great many ADs that ultimately will be found not to apply because they are excluded by serial number or for some other obvious reason.  While it may be slightly inconvenient to collect half a dozen serial numbers, it is even more inconvenient to search through thousands of them in ADs and service bulletins to determine if the AD applies.  Computers search numbers at blazing speed and make far fewer mistakes than people since they don't get distracted or bored.  Searching by model or series alone is very simple - and very misleading. These types of searches are also incomplete because none of them deal with appliance ADs.

A single aircraft search including all the documentation cited above is $59.  The supplied documentation is in PDF format and may be printed on your own printer for a permanent record.  Experience has shown that an AD Search Report delivered by ADR avoids 4 to 6 hours of mechanic time and is usually far more accurate and complete.  If you're a mechanic or inspector you already know the value of a proofed AD list.  If you're an owner you can save hundreds of $$ by obtaining this report and handing it to your mechanic or inspector.
