Martin B-26 Marauder

Aircraft Background:
The Marauder, a medium-range bomber, posted the lowest loss rate, about 1%, of USAAF combat planes during World War II. The B-26 was used most effectively for bombing raids on railroad depots, bridges, and airfields, and it developed an excellent reputation as a dam buster

Our Aircraft's History:
MAPS B-26, the 99th Marauder built, crash landed in British Columbia, Canada, on January 16, 1942, five weeks and five days after Pearl Harbor was bombed. Efforts are being made by several members of the MAPS Air Museum to restore it to flying condition. A book about the crash landing, including a personal account by co-pilot Lt. Howard Smiley, is available in the MAPS gift shop. Out of the Wilderness: Restoring a Relic was written by Lee B. Morrison of New Philadelphia, Ohio.

As is too often the case, when a part of an airframe is damaged or missing, often there is no option but to recreate, from scratch, the missing parts.  In this example, we're looking at internal ribs for the B-26 Marauder's ailerons.  These parts were either missing, or damaged beyond repair, so the restoration team had no choice but to recreate the parts from scratch.

What is a Cleco?  A Cleco is a spring-loaded fastener used to temporarily hold two pieces of sheetmetal together until they can be permanently joined together, usually by riveting or bolting.  Mostly used in the aircraft building process, they also appear in racing when building up the race car exterior.
