Listers,
FWIW - I have a Falcon altimeter that I installed in my RV-6A about four years ago. The plane has been flying since February 2005 and has about 130 hours. The altimeter has been certified twice to 20,000 feet per FAR 43 App. E at an FAA repair station with no problems, the latest check in February this year. I even posted and e-mail on the RV-list indicating my delight in this reasonably priced, Chinese made instrument being so precise and reliable.
A week ago in checking the cockpit in preparation for a flight, about two weeks since my last flight, I found the altimeter reading about 4000 feet. In in the process of trouble shooting, I disconnected the static line from the altimeter and found that it was still reading 4000 feet. The problem was obviously internal in the altimeter. I removed it from the instrument panel and took it home. After a week on my desk, the indicated altitude has increased to about 9000 feet and is still slowly climbing.
Consulting with the Wultrad folks I found that the instrument could be overhauled for $150. Since the current price is about $250 this was not attractive. And, since my confidence in the reliability of the instrument had been destroyed, I "bit the bullet" and purchased a United, TSOd altimeter at about three times the price of the Falcon. If you, have one of these you may want to keep a close eye on the field altitude at the correct altimeter setting. I noticed a small increase in the indicated field altitude a few weeks before the very large increase I mentioned.
Best regards,
Richard Dudley
