On March 28, 2021, about 1428 pacific daylight time, a Cirrus SR-22, N644SR, was substantially damaged when it was involved in an accident near Marana, Arizona. The pilot and passenger were uninjured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

The pilot reported that while enroute to destination airport, the airplane experienced heavy vibrations and moments later a complete loss of engine power. He attempted to maneuverer to a nearby airport but determined that he did not have the attitude. He attempted to deploy the airplane's parachute to no avail. He then selected a dirt road and made an off-airport landing, the right main landing gear
collapsed, and the right wing impacted the ground. According to the pilot, oil was seen streaking down both sides of the cowling.

The airplane was relocated to a secured facility for further examination.

The Pima County Sheriff’s Department confirmed that a single-engine aircraft made a crash landing on Pump Station Road in the Avra Valley area near Tucson Sunday.

One man and one female whose age is unknown were in the plane when it crash-landed. Both escaped the incident without injuries, said Deputy James Allerton, Pima County Sherriff’s Department spokesperson.

The roadway will be closed between Avra Valley Road and El Tiro Road while the Sheriff's Department investigates.

No further information was immediately available.

The area is known for its parachuting and aerial recreation, according to Allerton.

  1. Lost power after departing Tuscon for John Wayne, diverted for KAVQ, then redirected for KMZJ but came up short. Easy to see on track playback.

  2. Great outcome! Looking at flightaware, pilot did a good job establishing best glide speed and flying the airplane. Interesting to note real life performance numbers here. Roughly 7200' descent in 6 minutes. 1200' per minute at roughly 105-110mph average speed.

    1. That is right by the numbers. I was taught in the event of an engine out like this to set AP at 91 kts indicated (best glide speed) and then work the emergency. Of note on this one the pilot pulled the CAPS handle at 1500 but it did NOT deploy. Will be interesting to see the reason. According to the year it should of had a repack and update to the firing system in 2016 or 2017.

    2. Where did you hear that the CAPS failed to deploy?

    3. isnt that the deployed chute handle you can see dangling in the first picture?

  3. Found a decent road to land on. No traffic or posts. Aircraft can probably be repaired to fly again.

    1. I’ve always heard when those planes come down on the chute they’re basically totaled. This one looks like it’s damaged more than what it would have been had it landed under the chute.

      You’re right though, still doesn’t look too bad.

    2. Chute landings include riser rip-out from the fuselage skin and big-time gear overload. This one has damage typical for Cirrus runway landing veer / runoff incidents.

      Significant damage to a composite aircraft can send it to salvage auction when a riveted aluminum aircraft with similar damage might have been repairable.

      Would be interesting to see data on how many Cirrus aircraft that sheared off a main gear leg or damaged a wing returned to service. Might be zero.

    3. The chute deployment doesn't do any more damage than has to be done to service the chute. The repacking requires that they puncture the fuselage and then repair it later on. The damage doesn't come from the deployment, it comes from landing at a speed equivalent to a 10-foot drop. Even still, I've been told that somewhere around 25% are returned to service - but I imagine that has a lot to do with the price of the aircraft. I'm sure if you pull the chute on one of the $1M late model ones, that things getting fixed.

    4. If repacking included replacing replacing the flat web straps that are embedded in the fuselage skin, a repaint would have to be done after re-covering the strap channels.

      That big-time gear overload from chute landing puts a lot of stress on gear mounting points. If Cirrus routinely returned planes to service, they would brag about it in their sales pitch.
