"Aviation Maintenance Alert for Cirrus SR20 and SR22 Aircraft
Notice Number: NOTC8337

The Chicago Aircraft Certification Branch has posted an Aviation Maintenance Alert for Cirrus SR20 and SR22 Aircraft.

This Alert results from an accident that occurred on May 27, 2018 in Houston, Texas where a SR-20 airplane crashed shortly after takeoff.The pilot reported that he could not maintain roll control of the airplane immediately after takeoff. The airplane began to roll to the left. The pilot was able to counteract with right aileron input initially, but the airplane continued to roll to the left. The pilot continued to use right aileron and trim, lowered the nose, and executed a straight-in forced landing just beyond the departure end of the runway. Examination of the airplane after the accident revealed that the left aileron actuation arm and attach bolt were missing with no associated impact damage. Further investigation indicated that the safety wire was missing from the actuation bolt.

Recommendations

As the bolt is readily visible during a walk around inspection, we recommend that all owners and operators visually verify the presence of the required safety wire before further flight. If safety wire is not present, have a qualified maintenance provider correct the situation before further flight.

In addition, Cirrus aircraft will be updating their recommended pilot preflight walk around to better define the examination of the Aileron area and the maintenance manuals to emphasize the requirement of proper safety wiring the associated hardware. We recommended that all operators adopt the new manual practices and revisions.

The safety wire isn't "missing" it was never reinstalled after maintenance.
I am sorry to say this was just a case of crappy maintenance.
Safety wire "never" goes missing, When installed properly it does it's job.

This kind of thing chaps my big ol' Old Guy Butt!!!

It's interesting that the bolt in question is installed with the head down. The normal convention is to install them with the head up so they won't fall out if the nut comes loose. Speaking of nuts, I didn't see any kind of nut on the upper end of that bolt. Maybe it's screwed into something, I dunno'...

I think it just threads into the bracket, no nut.

Nope, no nut, just the one that didn't safety wire the bolt.
