Paschen’s Law

Every pilot performs a magneto check before takeoff, hoping to discover an ignition problem while still on the ground. It's always better to find a problem before becoming airborne than after. Unfortunately, some ignition system problems simply don’t...

No Droopy Drawers: Resizing the EarthX Battery Tray

Most everyone has heard about the newly approved EarthX battery STC for the Cirrus fleet. I’ve been following the project for quite a while and was excited when my installation kit finally arrived. A friend and customer even 3D-printed a test-fit EarthX battery...

Frankenclamp

For the past couple of years, the Cirrus community has been deeply engaged with Airworthiness Directive 2024-09-09 addressing turbocharged exhaust V-band clamps, specifically, the lack of readily available replacements. Just a couple of weeks ago, the issue came up...

Not Old… Yet: Early Aging Aircraft Issues in the Cirrus Fleet I’ve spent the majority of my career working on old-school, metal airplanes—many of which are now 60-plus years old. With these senior aircraft, there are significant maintenance issues directly related to...

 Zed, We Have a Bug!

I am a confirmed subscriber to the Reliability Centered Maintenance process. A part of that is to not euthanize an engine until proper testing has been completed and confirms the need to take drastic action. There are many articles of harrowing images of metal in the...

Little Fuse

Every new iteration of the SR series presents new opportunities for owners and maintenance providers to learn all the changes that aren’t in the sales brochures. The G7 is no exception with the really nice upgrade in the Garmin avionics suite. Changes were made with...

Navigating Maintenance Responsibilities

I was recently performing incoming operational checks on a Cirrus that arrived for its annual inspection, and I noticed an interesting semi-non-maintenance topic, VOR checks. A VOR check is not part of the minimum scope and detail of an annual inspection according to...

RED X Roulette Or Digital Isolationism

Back in my heavy iron airline aviation days in the avionics world, I tested and worked on the aircraft’s FDR (Flight Data Recorder). The FDR employed today with its massive storage capabilities is a far cry from what I used to work on that only recorded four...

Airworthiness Directives and the Power Lever

We’ve all been very distracted and entertained by the recent FAA Airworthiness Directive issued against the power lever on our Cirrus SR series aircraft. In following a couple of the forum threads relating to it, I noticed some voids in the understanding of...
