Low Time 1959 G18S “Twin Beech” N18G,

Executive Aircraft

This low time, nicely equipped and meticulously maintained Super G18S Beechcraft is at the top of its class and is ready for the most discriminating buyer. It is among the very best of the remaining Twin Beech’s and is eager to please a new owner for years to come.

A SEARCH FOR THE BEST

“Twin Beech” and “Stoltzfus” have been synonymous since 1963 when an ex-Navy SNB-5 joined the family and became the first of many from an AT-11 and JRB-4 of the C18S series, to an H18S, including a fleet of Hamilton Westwind III turboprops.

After operating these aircraft for tens of thousands of hours, the late Karl D. Stoltzfus of Dynamic Aviation (previously K&K Aircraft) knew exactly what he wanted in his final Twin Beech acquisition.

He finally found it in G18S, N18G (then N565US), the pampered, low-time, “never a freighter” Beech that he was looking for. Regal, beautiful but not glamorous, this was a practical airplane that he could let his grandkids or friends touch and ride in without worrying about fingerprints or snack crumbs. He bought it in 2019, and since then it has earned the affection of everyone at Dynamic who has been privileged to engage with it.

“Hangar Queen” took on new meaning with N18G! Rod Moyer, Dynamic’s Chief Pilot with many hours in turbine DC-3’s (elite among taildragger aircraft) says, “As to my heart-throb, Miss Amelia, there is only one airplane I’ve flown in my career that has made my heart skip when I walked up to it . . . . every time . . . . without exception. . . . and not because of fear or nervousness, but because of joy and anticipation. It was N18G – she stole my heart.”

A NEW DAY

A “Twin Beech” like few others today, and named “Amelia” because of her role with Nauticos in their search for the Amelia Earheart crash site*, N18G has fulfilled its assignment at Dynamic Aviation and awaits its next proud owner.

Sharing the ramp with a younger sibling who can only dream of taking her place in the annals of aviation folklore, Amelia sits poised and unthreatened like a beautiful, mature lady whose charm overpowers her otherwise obvious signs of aging.

FUTURE PARTS, MAINTENANCE

The renowned 450-HP Pratt & Whitney R-985 engine is known for its reliability, and because of their high demand in the agricultural and vintage aircraft fleets several excellent shops will be overhauling them for years to come. Parts are readily available.

Airframe parts are readily available as well. The late Karl D. Stoltzfus Sr. had accumulated a huge inventory over the years, and his son Karl, of Select Airparts in Weyer’s Cave, VA, recently added it to his already huge Beechcraft parts inventory.

PRICE: Asking price is $375,000 with a January, 2025 Annual, and several spare rotables.

 LOCATION: Aircraft is based at Bridgewater Airpark, Bridgewater, VA. PLEASE MAKE AN APPOINTMENT to inspect the aircraft.

 LOGS: Records are now in the Adlog system with detailed Dynamic Aviation entries including component and accessory records, progressive compressions and more.

 FAA FILES: I will email the FAA files to a serious prospective buyer.

*As recounted by Captain Rod Moyer, who flew this project:

   “In 2020 Karl (Dynamic Aviation) was approached by several retired Collins engineers who were now working with a group called Nauticos, who was preparing their 3rd excursion in the Pacific in search of Amelia Earhart’s Lockheed aircraft.

   On two prior missions, Nauticos had used ground mapping technology tethered from a research ship, and had mapped an area the size of Rhode Island. However, not succeeding, they sought to replicate the final moments of Amelia Earheart’s radio transmissions with the Coast Guard Cutter she was in contact with. In order to do this, they needed a Lockheed aircraft, or one of similar design, as well as an ocean vessel. In possession of the same radio equipment Earheart had in her Lockheed, they were put in touch with Karl through a mutual friend. Once Karl and Michael became aware of the back story and their intentions, it became an easy “yes” to help them reach this goal.

   Over the course of several weeks, N18G was integrated with a series of vintage radios as well as modern computer and communications equipment. Likewise, a vintage Chesapeake Oyster Buy Boat from the Chesapeake Bay area was being configured in much the same manner to replicate the Coast Guard Cutter.

   For the test flight, the boat was positioned approximately 5 miles off the Virginia coast and N18G flew a straight line from overhead, out to approximately 150 miles, stopping every 10 miles or so to make a steady 360-degree turn. On board were two engineers, a lady who transmitted the exact same words spoken by Amelia, and a videographer. The idea was to exactly duplicate what was heard on the Cutter. The 360-degree turn, and distance, would then also give bearing and range information since the position of the Cutter was a known fixed location. 

   The flight was deemed successful, and over the course of the next four years all of the data was meticulously analyzed, preparing them for their next oceanic survey.”
