Re: Safety Alert Hi Frank, The LH and RH pedal support tubes are parallel with only approx 1/8" between them. On the specimen airplane, this was not enough to provide clearance for the tube support brackets to fit in between the tubes (114 IPC Fig 2-41, Callout 40). The steel tube cut the...

Re: Safety Alert Hi All, Smoking gun! Our incredible wizard of Commander histories, Judi, found the smoking gun! An incident that found its way into one of the aircraft databases, but not the logs, 9 months after the airplane got its COA. Same exact failure, clearly explaining the...

Re: Safety Alert Hi All, Thanks all, and keep those reports coming. See direct pics attached of this specimen. The weld quality is such that I wonder if a previous repair was accomplished, am reviewing the logs again. Also we found interference between the LH assy support bracket and RH...

Re: New Shimmy Dampners Thanks for your call earlier about the new dampers. We do also still have our kit available for rebuilding the OEM damper: our SK-100, $25, which includes the balls and useful nylon rods for installing the rings without damage. If you want to order one of those kits...

Re: Safety Alert Hi All, Only a few inspection reports thus far, helpful, but not statistically significant. Can we get some more? Thanks, Jim

Re: Safety Alert Hi Joel, Thanks very much for checking your airplane! Others? It was actually the other crank that failed, did you inspect both sides? It is the LH pedal support shaft, but the crank is on the right hand side of the tunnel. Jim

Re: Safety Alert Hi Lawrence, How would we know if we are talking about 1 airplane unless we all check our airplanes? And to all: While every annual should, and hopefully does, include an inspection of the flight controls, once you have carefully examined this particular weld you will...

Re: Safety Alert Hi All, Check your airplanes. We will be disassembling the subject failed shaft assy for further inspection. Corrosion may have seeded the failure, but clearly the progression was due to mechanical loads. Preliminary review of the load scenarios points to braking loads...

Re: Safety Alert Hi Joel, At the moment, I don't see how pilot over-force could cause this without his/her foot passing through the firewall. Jim

Hi All, Check your airplanes: We have encountered a 3400-hour 112 with separation of the left hand pedal shaft crank from the pedal support shaft. See below IPC page and pics. Although we guess the original crack and fatigue started some time ago, this specimen airplane progressed from...

Hi All, Hartzell fronts SuperStream with Top Prop! Great news for 112, 112A, 112B, 112TC and 112TCA owners considering SuperStream, three-blade, or both: The Hartzell HC-E3YR-1RF/F7392 three-blade Top Prop may now be combined with Aerodyme SuperStream at substantial savings. For those of you...

Re: Seat Track Repair Kit Oops, bearings of course :)

Hi All, Many of our seat tracks are in trouble. Some of you will need new tracks and I understand that Glenn and others may be investing some time and money into that effort. Meanwhile, many tracks are repairable, in place, with proper tools. Aerodyme is pleased to now offer a track repair...

Re: Green, or Not! Hi All, My recent gear system advice needed a clarification that pin-lock actuators (112 s/n 1 thru 380) generally cannot be adjusted to achieve any appreciable actuation cushion (but are cursed to dwell on the hairy edge). Revised attached. Jim

Re: Super Commander owners Hi All, Here's some 580 Super Commander actual flight data: Note the weight, OAT, and tailwind conditions for Jeff's 10K cruise climb over the Sierra Nevada's in 25 nm. The climb to 22K was my Vy climb test flight in Vermont to determine service ceiling, tagging...

Re: Green, or Not! Hi All, Gear collapses continue... I have put some of my earlier forum advice down on a printable sheet for those interested. There is pertinent Maintenance Manual information, and excellent other advice available here on the COG site, but dealing with these gear systems...

Re: New 3-Blade Prop STC for 114/A Hi John, I am working with Hartzell to add the F7392 three-blade 112 prop to Aerodyme's offerings and may be able to quote you a good price.

Re: Better IO-540 Overhaul There is a quality range on this: Let's say 2 guys 2 days for the slam bam. Add some for TLC attention to the many things that are asking for attention at 2000 hrs. Jim

Re: Better IO-540 Overhaul Hi Paul, Here's the current engine pricing from the Air Power website. Jim
