Keystone Helicopter, a subsidiary of Sikorsky Aircraft, signed an agreement to provide maintenance and completion services to Seacor’s aviation division, which includes Era Helicopters, Era Leasing and EraMed. The Seacor fleet includes AgustaWestland A109s, A119s and AW139s; Eurocopter EC 135s, EC 145s and AS 350s; and the Sikorsky S-76++.

EraMed is located at the same Coatesville, Pa. airport as Keystone Helicopter.
Keystone also announced delivery of its first S-76+ outfitted with the new Silencer interior. Silencer weighs about 100 pounds less than the standard interior and offers sound levels of 81 dbs, which is lower than the fleet average. The new interior’s benefit is lower maintenance costs, thanks to built-in access points that eliminate the need to remove the entire interior furnishings during routine inspections.
