In the spring of 2010 WestJet Airlines of Canada was looking for tooling to help with the removal of Landing Gear for our fleet of Boeing 737NG aircraft. This tooling requirement was based upon two factors. The first being inspections of the MLG forward Trunnion pins as mandated by AD 2009-26-04 which could have resulted in the necessity to remove the main Landing Gear and the second being the commencement of our Landing Gear overhaul program which was to begin in 2011. Selection of the "Omni Arm tool" was based on the quality and versatility of the tool itself, plus dealing with the personnel that actually manufacture and sell the Omni Arm. Historically, WestJet has found that smaller companies with niche' products tend to provide better customer service and this has certainly been the case with "D Check". The owner of the company (Jeff Barkes) personally flew to Vancouver, British Columbia from Georgia to provide onsite training for WestJet personnel to ensure that our folks were comfortable with the tool and also to make them aware of its capabilities. Jeff is also working on an additional aid that is specifically for the 737NG that would make MLG changes even easier.

In summation, WestJet is very pleased with the quality of the tool, its potential and all dealings with the manufacturer D-Check Developments, Inc.

We here at AAR Aircraft Services - Miami have had great success with the Omni arm. Originally we used it to replace the main landing gear and nose gears for the Boeing 717's. The use of this equipment has been a great assistance to the technicians accomplishing these tasks. With D-Check's support we have been able to modify and use the Omni Arm for 737 NG's as well as 727 gears. Just wanted to take time to thank you for your continuous support.

I would like to thank you for your prompt reply to my questions about your tool, and also like to congratulate you for designing and building a tool that is truly mechanic friendly. Not only is your tool simple to use, it is functional and extremely versatile. I have never used a landing gear installation tool that could pick a landing gear out of a crate, position it so the machine shop could work on it, and then roll it to the A/C and install it. All this, without once repositioning or readjusting. I was also impressed with the close tolerance construction and super fine adjustment capability.

AirTran Airways and D-Check Developments, Inc. have enjoyed a long-standing relationship since the inception of D-Check in 1997. Value Jet, the predecessor of AirTran, took delivery of the first production Omni Arm Landing Gear Changer in 1997. Since 1999 D-Check has provided a variety of solutions to AirTran's tooling, equipment and aircraft repair needs. Fast response emergency services have also been provided for engine repairs requiring a skilled machinist for the BR715 and CFM 56-7B. D-Check has devised and manufactured tooling such as thrust reverser and nose cowl turnover slings, engine work stands, and most recently a jacking, positioning and clocking devise for the Integrated Drive Generator on the Rolls Royce BR715 engine. D-Check is a reliable partner always responding to our diversified needs quickly, efficiently and correctly to assure timely repairs in often difficult conditions. We will continue to use D-Check's services in the future, trusting the quality of their work to always meet or exceed our expectations.

I am happy to provide a reference for D-Check Development, Inc., manufacturer of the Omni Arm. I have known Jeff Barkes - President of D-Check for many years, dating back to the 1990's with Northwest Airlines and continue to work closely with him in developing custom tooling for AirTran Airways. Jeff's experience allows him to understand the environment / challenges the industry faces and apply this knowledge to create some of the best user-friendly tooling available.

I am confident you will find the Omni Arm an innovative tool that will serve you well for many years providing a safe, efficient means to remove and install landing gear assemblies. The tool is easily adaptable for nearly all aircraft models and Jeff can provide additional custom made adapters for your military operations.

I have enjoyed seeing Jeff's business, as well as his customer base grow though the years and am happy to recommend him to anyone seeking ground support equipment and/or machine shop fabrication work. Please feel free to contact me at anytime.
