CAPT. CHESTER R. RATCLIFFE, JR.

An Air Force H-43B HUSKIE has claimed a second international distance record within a three-week period. Both of the records were previously held by the Soviet Union.

Established on July 5th was a straight-line distance record of 900 miles. The flight originated at Hill Air Force Base, Utah, and ended eight hours and 27 minutes later near Springfield, Minn. Pilot on the flight was Capt. Chester R. Ratcliffe, Jr., Commander of ARS

Det. 24, CARC, MATS; Kincheloe Air Force Base, Mich. The previous record of 761.027 miles was set by a Soviet Mi-1 helicopter on September 21, 1960.

On June 13th, three weeks before Captain Ratcliffe's flight, Capt. Richard H. Coan of ARS Det. 52, EARC, MATS; Charleston Air Force Base, S. C.; flew an H-43B 656.258 miles around a closed course near Mono Lake, Calif., to break a record of 625.464 miles set by a Soviet Mi-1 helicopter in June, 1960.

The H-43B, manufactured by Kaman Aircraft Corp. of Bloomfield, Conn.; now holds five international records for helicopters. The three other records held by the HUSKIE are: Altitude without payload, 32,840 feet, set Oct. 18, 1961 by Lt. Col. Francis M. Carney of Stead Air Force Base, Nev. Altitude with a 1,000 kilogram (2,204 pound) payload, 26,369 feet, set May 25th, 1961, by Capt. Walter C. McMeen of Luke Air Force Base, Ariz. Both records were previously held by Russia. Time-to-climb to 9,000 meters (30,000 feet) in 14 minutes, 11 seconds, also set by Colonel Carney and previously held by France.

The H-43B, which is powered by a Lycoming T-53 gas turbine engine, is an Air Force utility helicopter now stationed at nearly 50 Air Force bases around the nation and overseas. Air Rescue Service, MATS, has established the HUSKIE as its standard helicopter and is using the aircraft for local base rescue duty. K

start switch, and deenergizes the complete starting system. The complete starting system cannot be energized again until N1 RPM decreases below 28 to 30%. However, it is possible to make an air start with N1 RPM in excess of 30% as only ignition is required to start the engine. This can be accomplished by depressing the start button and holding it until the engine is started.

This action provides a path for current flow direct to the ignition unit, as stated previously. The current for the ignition system does not flow through the speed switch.

Since proper functioning of the speed switch is necessary for engine starting, it is relevant to discuss the effects of a malfunctioning unit. Known speed switch mal-

Helpful Info From Det. 44

As a means of reducing tow-bar fitting wear on the H-43B nose wheel, personnel attached to ARS Det. 44, EARC, Westover AFB, Mass.; have inserted rubber liners as shown. An AN931B24-28 grommet may be used or a similar liner can be cut to fit the towbar access hole. The fore-and-aft motion experienced when towing is also partially absorbed by the liner which can be used on H-43A, HOK-1, HUK-1 helicopters as well. (USAF photo)
