WW2 US Army Air Force – EXHAUST INSPECTION PLACARD DATA PLATE – STINSON – NICE

You are bidding on a VERY NICE original WW2-era American Aircraft Exhaust Inspection Placard, believed to have originated from a Stinson aircraft! This type of maintenance instruction plate was installed on aircraft to identify the required inspection interval for the engine exhaust system.

During the 1930s and 1940s, Stinson Aircraft Corporation manufactured numerous civilian and military aircraft, including the SR-series Reliant and military UC-81 and AT-19 variants. Engine exhaust systems required regular inspection because of the extreme temperatures, vibration and stresses encountered during operation. Exhaust pipes and associated components were particularly susceptible to cracking, corrosion and deterioration, making frequent inspections an important part of aircraft maintenance. This type of placard reminded maintenance personnel to remove the protective cover and inspect the exhaust pipe after every 20 hours of operation.

Made of aluminum, this Data Plate is in EXCELLENT used condition! Some slight marks and  wear due to use and age, but nothing that detracts. The original wording, “REMOVE COVER & INSPECT EXHAUST PIPE EACH 20 HOURS,” remains clearly legible, with both original mounting holes intact. This came to me with a large quantity of WW2 Trainer, Liaison, and Reconnaissance aircraft parts. An ORIGINAL and increasingly difficult-to-find piece of Stinson aircraft equipment that would make a FANTASTIC addition to any vintage Stinson restoration, aircraft interior display, or advanced American aviation collection!
