Anyone know of where Diamond keeps a list of the MAMs and OAMs? The maintenance manual references a bunch of different ones, but never describes what they are, and the Diamond support site has no list I can find. Additionally, web search typically comes up with nothing.

I made a list of the OAM's and MAM's for a DA 42. Helped when reading through the AFM/POH to see what applied to the particular airframe I was flying. A more comprehensive list would be helpful for Diamond to post online.

The tech pubs website has a "List of Applicable Publications" for each model. Here's the link and the current list for the 40-180.

MÄM, a M andatory ÄnderungsMitteilung

and

OÄM, an O ptional ÄnderungsMitteilung.

Literally translated they are mandatory and optional advisories of change.

From a linguistic point of view, it is very ugly to mix English and German, but even Germans and Austrians sometimes understand certain words better in English and so they mixed it. What do engineers know about languages? :D

Both, Diamond Austria and Diamond Canada use this term. It is of no use to the end customer and was meant to describe ongoing changes in their production so that certain MÄMs or OÄMs were added to the POH helping to distinguish the state of equipment of the individual airplane.

AT one point when I was deeply involved in the maintenance records of my new DA42 I started working on a web service that would keep track of all of the AD's, SB's, and so forth for a particular model. When my plane was having the logs examined by the Diamond Factory they sent me a spreadsheet of the applicable AD's and SB's with the ones it was missing highlighted. They then asked for those files back, saying they had been sent out in error.

To me this is typical of the sort of liability-fears that govern a lot of the industry. They didn't want to release something that claimed to be a definitive list, since if there was an incident related to that data being accurate, the company would be liable for it. When I was working on my possible service I called the factory and my contact there said "no way, no how" to whether we could have an updated spreadsheet for various models.

I don't know if that policy has changed. If I were the FAA I would make it mandatory that an API report all pertinent AD's and SB's and so on for a given model.

Attached is a list I made of all the OAMs and MAMs I could find or infer for the DA40 from the Diamond website and the AMM, with the approximate dates implemented. Anyone with additional info, please add to the list and repost.
