Globe Swift

[metaslider id=1087]
I first flew a Globe Swift in 1961. It was a 125Hp beauty that Inga and I rented and flew from Charleston, WV to New Jersey and New York. Our baby son KJ slept behind us on the hat shelf above the baggage compartment. I was a young pilot with less than 100 hours logged. All worked out fine until the windscreen was covered in oil on departure from Syracuse. A turn back to the field and emergency declaration followed. The engine froze as we taxied off the runway. The owner wasn’t upset when told his plane was AOG Syracuse. He said he had a new engine on hand and was planning on the change. Whew!

Almost 3,000 flight hours later I went to the 2008 EAA Airventure. There was a row of smiling swift cowls, and the bug bit hard. I searched for four months and found N141PW in the hands of Pat Waters of Mt. Plesant, SC. N78314 was it’s original factory registration number. It has been a wonderful airplane and has received many upgrades since it arrived in our hangar.  Unfortunately I must now sell the plane.

Emergency Locator Transmitter

July 3, 2016

For the RV-7 we purchased an ACK-04 ELT.  It transmits on 406 as well as 121.5 MHz. and connects to Garmin G3X providing  NEMA 0183 GPS position data.  The installation manual requires the ELT be mounted parallel to the aircraft forward axis; and also recommends it be near the rear of the aircraft.  Unfortunately a rear mount would make the transmitter inaccessible to CFIT survivors.

ELT ON TUNNEL COVER

I have chosen to mount the ELT on the tunnel cover forward of the seats.  While this may increase the risk of ELT damage in a CFIT, an impact of that magnitude would likely eliminate survivors.

TUNNEL REINFORCEMENT

Another recommendation is that the mounting provide deflection stiffness so spatial movement is no more than 0.1 inch under a pressure of 100 pounds.  The pictured reinforcing channels do that.

ELT AND FUEL BOOST PUMP & FILTER

The electric fuel boost pump is mounted on a separate section of tunnel cover.  An additional cover over the pump & filter will separate them from the ELT.

Autopilot Pitch Servo

June 20, 2016

The Garmin autopilot pitch servo is furnished with a mounting plate and specific instructions for installation in a Vans RV-7.  The plate becomes riveted to the center floor rib behind the baggage bulkhead.  The servo moves the elevator push-rod via its connection to the bellcrank.

Care is given to adjusting the length of the servo to pitch bellcrank connecting rod so that no over-center lockup can occur.

INSTALLED SERVO

Wires from the db15 socket connect the servo to both the instrument panel autopilot controller and to the pitch trim servo located in the left elevator.  Torque sensors in the pictured servo generate signals fed to the pitch trim servo.
