Carson Helicopters

Carson Helicopters, Inc is a helicopter operating company based in Perkasie, Pennsylvania, United States. Carson operates a fleet of Sikorsky S-61 helicopters in aerial lift services and aerial firefighting. Carson is known for its development of the "Carson Blade" for the S-61 and H-3 Sea King.[1] In 2010, Carson Helicopters, Inc. partnered with Sikorsky Aircraft to develop and manufacture the S-61T, an upgraded version of the S-61 helicopter.[2]

In 2015, a federal jury found that a previous Carson Helicopters crash was caused by the failure of the aircraft's GE designed engine, specifically issues with the engine's fuel control with GE had previously been notified of.[3]

Upgrade Programs

British Royal Navy Upgrade Program

In 2007, Carson Helicopters partnered with the British Royal Navy to modernize its British HC4 Sea King Helicopters because British forces faced issues operating the Sea Kings in Afghanistan due to the country’s altitude above sea level and lower air density which contributed to a dramatic decrease in lift and forward speed.[4]

The upgrades included the replacement of the aircraft’s legacy metal main rotor blades with the Carson Composite Main Rotor Blade and to use Agusta Wesland’s five-bladed composite tail rotor. Within 12 months after installation, the upgrades were tested and deployed after receiving a UOR from the MoD.

The increased performance provided by the Carson Composite Main Rotor Blades enabled the aircraft to operate at its operational and design capability in hot-and-high environments without having to strip weight or decrease defensive aids, such as armor or weaponry and its associated ammunition.[5]

S-61T Program

In February 2010, the U.S. State Department signed an open-ended contract for as many as 110 Sikorsky S-61 Triton Helicopters("S-61T") for U.S. diplomatic transportation and cargo services.[6]

The S-61T, which was an upgraded SH3H, included a fully modernized glass cockpit with digital screens and avionics, crashworthy seats, a modular wiring harness derived from the UH-60 Black Hawk, as well as engine and transmission improvements. Upgrades also included the Carson Composite Main Rotor Blades which provided a 10 knot increase in cruising speed using the same horsepower and a 1750 lb. increase in lift.[5]

  • On 9 June, 2008, a fire was sparked in the Great Dismal Swamp National Wildlife Refuge which burned for 111 days.[7] Carson Helicopters had been in the process of completing a 1,110 acre clearing project to remove trees damaged by Hurricane Isabel in 2003.[8] A federal contract with Carson Helicopters allowed the company to keep cedar recovered during the clean up effort, the large majority of which was lost in the fire.[9] The fire was declared out on October 7, 2008. Total cost to suppress the 4 month, 4,884-acre blaze was estimated at over $12.5 million.[10]
  • On 5 August 2008 a Carson Helicopters Sikorsky S-61N (tail number N612AZ)[11] crashed on take off due to a design failure in General Electric's GT-58 Engine. A federal jury found that GE had previously been made aware of the design flaw in the engine. According to the NTSB, nine people were killed. These were the pilot-in-command, Roark Schwanenberg, 54, of Lostine, Forest Service safety official Jim Ramage, 63, and seven firefighters: Shawn Blazer, 30, of Medford; Scott Charlson, 25, of Phoenix, Ore.; Matthew Hammer, 23, of Grants Pass; Edrik Gomez, 19, of Ashland; Bryan Rich, 29, of Medford; David Steele, 19, of Ashland; and Steven "Caleb" Renno, 21, of Cave Junction. The copilot and three firefighters escaped the burning wreckage and survived with serious injuries.
  • In February 2013, two former Carson Helicopters employees, Steven Metheny and Levi Phillips, were indicted for conspiracy to defraud the United States, with Metheny also being charged with other violations including mail fraud, wire fraud, making false statements to the Forest Service, and endangering the safety of an aircraft in flight. The U.S. Attorneys office also accused Metheny of "stealing continuously from Carson," and using "Carson funds to buy jewelry and other personal items for himself and his wife and to renovate their residence and sold Carson helicopter parts and equipment and diverted the proceeds for his own use."[12] The findings of the National Transportation Safety Board in 2010 stated there was “intentional wrong-doing” by Carson Helicopters that under-stated the weight of the Sikorsky S-61N helicopter and over-stated its performance in their bid to the USFS on $20 million in contracts for seven helicopters. A Federal jury found that the August 2008 accident was 23% due to the actions of Metheny.[3] In June 2015, former Carson VP Steven Metheny was sentenced to 12 years, 7 months in prison for falsifying documents that led to the 2008 crash.[12]
