You would have a hard time finding a nicer Raven II that flies as well as N1958C. You need to see and fly it to appreciate the value of this Raven II for the price. This ship was just overhauled at 12-year interval. The overhaul was just completed by Midwest Aeronautical Helicopter Services, an experienced Robinson R22 and R44 Service and Overhaul center.

This 2013 Robinson R44 Raven II is air-conditioned and IFR-trainer-equipped. N1958C, serial number 13000, had 2163.9 total airframe hours at its first-run, 12-year, 2200-hour major overhaul. All ADs & SBs have been complied with.

Exterior color is IMRON Dark Indigo (Blue) Pearl Metallic with Vinyl Gold-Metallic Trim. The cabin features a new tan leather interior with matching carpets, bubble windows on all four doors, Bose powered headset jacks at all four seats, and 5-point front seat belt harnesses.

The Lycoming IO-540 engine was overhauled by Pinnacle Aircraft Engines and has 568.7 hours since engine overhaul. A brand-new Robinson “Quiet” muffler and complete exhaust system were installed at the aircraft overhaul.

9-hole panel, fully equipped from Robinson; can also be used as an IFR trainer.

"The best overhauled R44 we've ever seen"

Major Added Value:

  • EVERY overhaul is performed using a complete Robinson Helicopter Company factory-made Overhaul Kit. We don't cut corners like some field overhaul providers. Our overhaul process follows the same rigor of a factory overhaul - but at a much lower price.
  • EVERY overhaul includes a major engine overhaul performed by a leading overhaul specialist.
    • Midwest Aeronautical commonly works with Signature Engines of Cincinnati, Ohio. Their company has been overhauling aircraft engines since 1998. Aviation Consumer Magazine has ranked Signature Engines one of the Top 10 engine overhaul facilities in the U.S. based on customer satisfaction.
  • EVERY overhaul is completed to ensure compliance with all FAA Airworthiness Directives (ADs) and Service Bulletins (SBs).
  • EVERY overhauled ship we offer includes bladder-lined fuel tanks ($10,000+ value) for added safety - and in anticipation they will soon be required by FAA Airworthiness Directive.
  • Overhauls are carefully & thoughtfully performed by experienced, professional Robinson maintenance experts.

Our Unique Experience:

  • As of mid 2016, Midwest Aeronautical has completed eleven (11) successful R22 & R44 field overhauls since achieving certification as a Robinson Factory-Authorized Service Center in 2005. We currently just completed our 11th major overhaul on a Raven II Factory Instrument Trainer.
  • Chief A&P Mechanic Charlie Duchek is also an experienced pilot & flight instructor (Commercial, CFI and CFII) with over 6,400 total helicopter hours- including over 5,100 hours as flight instructor in Robinson helicopters. He started flying helicopters in 1985 and earned his private pilot rotorcraft rating in 1986 – over 30 years ago. Charlie also has past experience as a Designated Pilot Examiner (DPE) for the FAA.
  • As former owner of the largest independent helicopter pilot training facility in the Midwest, Charlie has owned & maintained more than two dozen Robinson R22 and R44 helicopters since 1991.
  • Additionally, Charlie has a Bachelor's degree in Mechanical Engineering and a Master's degree in Engineering Management. Prior to his career in aviation, he ran a successful automotive repair business where he also worked as a professional auto mechanic on a wide range of both foreign and domestic vehicles, including all major luxury brands.
  • Charlie has been working on Robinson helicopters for over 20 years, is an experienced A&P mechanic, and has attended numerous manufacturer maintenance training courses including:
    • Robinson R22 Factory School
    • Robinson R44 Factory School
    • Lycoming Factory Engine School

Midwest's Overhaul Philosophy

We know that many potential customers are apprehensive about purchasing a Robinson helicopter that has been overhauled in the field by an Authorized Service Center. There are countless ways to cut corners on a Field Overhaul. Midwest doesn't do any of those. Midwest has been completing first-class overhauls for more than 10 years. Some overhaul facilities only overhaul or purchase selected overhaul exchange components from the factory. Midwest only buys the complete factory overhaul kit (including fuel bladder tanks, if required) and properly installs, tests, aligns, and rigs all of the items supplied in the Robinson factory overhaul kit.

What was in the RHC Factory-Supplied Overhaul Kit for our most recent overhaul (N186TC, Raven II) as an example:

What is done on a proper Midwest Aeronautical R44 overhaul?

Disassembly

First of all, the helicopter is completely disassembly down to the bare cabin sitting on the skids. During disassembly, all parts are thoroughly inspected and a list is made of additional parts that need to be replaced during reassembly based on normal wear and tear above and beyond those supplied in the factory-overhaul kit.

After disassembly, all the "core" items (items that will be overhauled at the factory and used in future overhaul kits) are shipped back to Robinson for evaluation and credit.

Then, a complete Factory overhaul kit is ordered and paid for in advance (including bladder tanks if required). Current price for that kit is $141,000.00 plus a Core Charge Deposit of $40,000.00. This does NOT include the cost of the engine overhaul, presently approx. $36,000.00.

Other parts and supplies are ordered to replace worn items or to comply with Airworthiness Directives (ADs) and Factory Service Bulletins that need to be performed.

Then, the lower structural frames are removed and sent out for bead blasting to bare metal, magnetic particle inspection, and two powder coats applied (primer and finish coat).

All sheet metal parts are evaluated and repaired or replaced as necessary.

Reassembly, Rigging, and Testing

All work is done in accordance with the procedures outlined in the Robinson Maintenance Manual. (It normally takes Midwest about 3 months to do a first-class overhaul from start to finish).

Midwest always supplies new Airframe and Engine Logbooks and a Current Pilot Operating Handbook (POH), along with a new Hobbs Hour meter to record flight time since overhaul.

All ADs and Service Bulletins are researched and complied with. Battery, Starter, and Alternator are evaluated and replaced if necessary. Skid shoes are inspected and replaced if necessary.

Hydraulic flight control systems are installed with new packings, etc. and pressure-tested.

Normally, new leather interior Seats are installed along with new floor carpeting, etc. This cost is in addition to the overhaul kit and engine overhaul cost.

After the helicopter is completely reassembled, the tail rotor and main rotor systems are "rigged" in accordance with the procedures called for in the Robinson Maintenance Manual.

After the first engine-start, the engine cooling fan, tail rotor assembly, and main rotor assembly are tracked and balanced.

During several hours of break-in and test-flights, the radios, instruments, gauges, and avionics are evaluated and overhauled or replaced as required.

All work performed is properly entered in the new 'post-overhaul' engine and airframe logbooks.

This is the RIGHT WAY to do an overhaul, and Midwest does them RIGHT !!
