A & P Testing and Certification

DME Services has one Designated Mechanic Examiner

 (DME), Steve Alcorn.

Providing A&P Oral and Practical testing and FAA certification since 2013, DME Services tests over 200 applicants a year.  As an independent, not affiliated with any 147 school, applicants from all parts of the United States and around the world use our services.

We advise all applicants to read the following publicly available documents in preparing for the Oral and Practical Exams. FAA information regarding the process to obtain an A&P certificate is available on faa.gov in faa-8083-30_ch13 Obtaining the Mechanic Certificate.

FAA information on Practical Test Standards, the basis for the Oral and Practical Exams, is available on faa.gov : Aviation Mechanic General PTS is Form FAA-S-8081-26A.  Aviation Mechanic Airframe PTS is Form FAA-S-8081-27A.  Aviation Mechanic Powerplant is Form FAA-S-8081-28A.


  The Oral and Practical exams cover 44 subjects. The Oral questions are downloaded from the FAA’s data bank for each exam.  As for study materials, the Oral questions are published in various Oral and Practical Study Guides.  ASA publishes one, as does Jeppesen and Baker’s School of Aeronautics. The 3 Jeppesen books are available from www.amazon.com .  They are called “A&P Technician General/Airframe/Powerplant Test Guide with Oral and Practical Study Guide”.

Scheduling and Oral and Practical Testing Fees

We offer testing times during the week and on weekends. For a full A&P test we allot one full day.  For a partial, such as an initial General and Powerplant, or retake, we allot a half day starting at 8 am or 1 pm. We prefer to schedule based on a phone call but will start the discussion based on an email request.  At the time of scheduling, we will advise on the cost and necessary documentation. 

We advise you contact DME Services as soon as you have a date in mind. 

We try to accommodate applicants special needs for scheduling sue to work or school.  Our weekend times fill up early.

Payment may be made by cash, credit card, PayPal, or Western Union.  Personal checks are not accepted.  

We try to accommodate needs for test time changes.but changes to test dates should be avoided if possible. There may be a cost assessment for last minute cancellations or changes made within two weeks of the test date.

At the time of scheduling there will be a request for copies of required documents.  These provide the necessary information for DME Services to prepare the paperwork for the tests.
