The U.S. Army Aviation Center conducted the Operational Test II OTII to determine whether the emergency repair shelter for the CH-47 helicopter meets the requirements of the approved material need MN during temperate and simulated Arctic conditions. Four shelters were tested from November 1973 through June 1974 at Fort Rucker, Alabama Appalachicola, FL and in the McKinley Climatic Laboratory at Eglin Air Force Base, FL. Several zippers on the sidewall of the shelter failed during the test, indicating a lack of durability. It was concluded that the emergency repair shelter will meet the requirements of the approved material need for temperature and Arctic climatic conditions when the durability problem is corrected.
