Falcon 10 N100CU, Leading Particulars:
AP105/FD109. Dual FD. Single FMS.

AP AMP – 562C-5C.

Pitch bump started, May 2022. Swap vg.  That solved it for months.

Pilots report all good.

Swap airdata controller. (Back to original position)

Hum in headsets

 

Stuck mic.  Seemed to start pitch bump problem.

Mar 2023.   Shutter pitch, humming headphones, could not hear atc. Stuck mic.

after finding burned plug at RH lav:
#1 FD/AP will not capture altitude, but (sortof) will track altitude

#2 FD will not GA.  RH GA will clear HDG select button, will not clear ALT select button.  When RH GA is held down, RH Vbars will go to 0 pitch or lower, then disappear when G is released.

Collins manual that shows the difference between 590A-3H, and 590A3K

1.5.16 590A-3H Air Data Control
The 590A-3H Air Data Control supplies an analog error signal to the flight control system that is propor-
tional to altitude error. True airspeed, indicated airspeed, and altitude programming voltages are also gen-
erated for flight control system use. The altitude error gain may be programmed with true airspeed, indi-
cated airspeed, or altitude, or set at a fixed value. The 590A-3H also provides signals for altitude preselect,
vertical speed hold, indicated airspeed hold, and Mach hold. The 590A-3H is contained in a 318-ATR short,
low case and weighs 2.09 kg (4.6 pounds).
1.5.17 590A-3J/3J1 Air Data Control
The 590A-3J/3J1 Air Data Control supplies to the flight control system an analog error signal that is propor-
tional to altitude error. True airspeed, indicated airspeed, and altitude programming voltages are also gen-
erated for flight control system use. The altitude error gain may be programmed with true airspeed, indi-
cated airspeed, or altitude, or set at a fixed value. The unit is contained in a 3/8-ATR short, low case. The
590A-3J weighs 2.00 kg (4.4 pounds) maximum. The 590A-3J1 weighs only 1.5 kg (3.3 pounds).

Aeronca Champ N82258

 

Aeronca 7AC Champion “Champ” N82258 S/N 886

The Aeronca Aircraft Corporation (AERONauticalCorperation of America)  Produced 7,200 of 7AC “Champs” in 1945 to 1948.  Derivative models are still produced today, as late as 2024.

The 7AC is a sought after antique, with thousands of flying example still airworthy.

The Heffley Family airframe is a Model 7AC, powered by a  Continental A65. Superior cylinders were fit during the rebuild.

  • Wingspan of 35 ft
  • Height of 7ft
  • Length of 6.55 21ft 6in
  • Cruise speed of 85 mph
  • Rate of climb of 370 ft/min

2006_02_08ChampPaintGoneBad

 

This is what happens when the paint process goes horrably wrong. This is the result of not sanding the primer after the last cote of primer. This video shows the paint peeling right off. We followed the STC exactly, and applied the first color coat over the last primer coat with no sanding. This is not wise, as we now know. Airtech markets its product as process that requires little sanding. While it is true that you are not required to sand as as much as Stitts, it still requires the coats to be “scuffed”.

2006_01_05ChampPaint
The Ailerons, and Elevators/Stabilizers, (not the rudder) installed on a spit for painting.

2005_12_29_ChampPaintBooth
We built a paint booth (Larger) from discarded metal studs and plastic sheeting. The intake is a 24″x24″x1″ AC filter with a box fan. (lowerLeft corner of the picture). The outlet is a filter connected to 1/4 of a LARGE cooling fan.  This evacuates the booth, as well creates a draft in the hangar that cause overspray to go west out the doors. Interestingly, the outlet fan filter FILLS up every time we paint. No overspray anywhere in the hangar though……

 

These are the cable fairleads

that will provide a cosmetic closeout for the rudder cables as they exit the Fusalage  under the stabilizers.

2005_11_27ChampWingSpit
This is the wing installed on the completed spit (larger). Copied from a comercial design, The rollers (larger) are metal lawn mower wheels with the tires cut off. The hoop is 1/2 inch electrical conduit bent with a conduit bender.
The wing spit is a complete success, allowing the wing to be coated fully on both sides without a 1 day wait for paint to dry. If we had to do it all over, 1″ conduit would have been stronger.  Also, the rollers could have been lower, allowing the wing to be 3 inches lower to the ground.

2005_10_15ChampGear
Here is a Sectioned (larger) gear oleo and strut.  We used this for a reminder of how all the parts came apart!
The Gear Case Frames almost ready to paint.  We included the tabs for the snare cables, even though the AD is complied with……

 

2005_03_18_ChampStrutPress
This press ended up not being required, as the gear did not need to be “Pulled” apart.

 

2005_01_08_ChampRightBrake
We disassembled one brake at a time, as they are quite complicated.  Brake OutsideAssembled,   Inside Exploded.

Here is the Fuselage before (Larger) Powdercoating, and one picture after (Larger) powdercoating

Fly in mode change veil without transponder

 

Conditions You Must Meet
To exercise this exemption legally under 14 CFR § 91.215(b)(3) and 14 CFR § 91.225(e)(2), you must adhere to the following:
  • Stay out of Class A, B, and C Airspace: You can fly inside the 30-mile radius (the veil), but you cannot penetrate the actual lateral boundaries of the Class B, C, or A airspace itself without explicit air traffic control (ATC) authorization. [1, 2, 3, 4, 5]
  • No later electrical additions: The exemption only applies if the airplane remains in its original non-electric state; adding an alternator or generator removes this specific legal protection. [1, 2]
Operational Details
  • Documentation: Ensure your aircraft’s original type certificate or airworthiness records verify it was manufactured without an engine-driven electrical system.
  • Flight Plans & Radio: While operating inside the veil, you don’t need a transponder or two-way radio. However, monitoring the appropriate local frequency (such as the tower or CTAF) for situational awareness is strongly recommended. [1, 2, 3]
