Why do so many Mooney owners seem to grimace when the conversation turns to fuel tank problems?
The vast majority of shops simply do not know how to deal with Mooney tanks: period, end of discussion! In our estimation, there are only a few (less than 10) shops in the U.S. where we would recommend you to take your Mooney for tank work. If an experienced shop has the proper tools and pressure testing equipment (usually shop fabricated), and Mooney Fuel Tanks Specialists (in fact, we call two of our guys; Fuel Tankologists) who are experienced with tanks, they are actually no problem. It is the almost total lack of expertise in the field nationwide which has given Mooney tanks a bad rap. Rarely do we have to actually completely strip and re-seal a fuel cell. Usually, we have the repair process down to a science and our repairs last as long as you own the Mooney; or longer. We can’t warn you enough to only have someone look at your tanks who both wants to, and is vastly experienced (having a long track record) in successful repairs.
