Plane crashes in Yorba Linda neighborhood, 2 dead 2 injured
YORBA LINDA, Calif. (FOX 11) - A twin-engine Cessna 414A crashed Sunday in a Yorba Linda neighborhood, killing two people, injuring two more,and setting at least one house on fire, according to the Orange County Fire Authority. The plane nosedived onto Canyon Drive about 1:45 p.m., OCFA Capt. Cameron Rossman said. (www.foxla.com) Más...Sort type: [Top] [Newest]
I seem to have a vague memory of an AD on the 414 having to do with turbo exhaust burning through a wing spar....? something like that...? Anyone remember anything like that? A spar failure sure would explain what seems to have happened.
Just found some info from AOPA about spar problems & ADs (I'm interested because I flew all the 400 series Cessna for many years). https://www.aopa.org/advocacy/advocacy-briefs/regulatory-brief-faa-proposed-twin-cessna-wing-spar-ads
The AD is AD75-23-08R5 and applied to pretty much all C300 and C400 aircraft. As I recall, it required a 25 hr visual inspection, and 50 or 100 hr pressure test inspection.
I can tell you from experience, one does not want an exhaust leak. The C320 I was flying had such a leak, within 15 hrs of annual inspection where the pressure check and visual inspection was signed off.
The indications on the affected engine were puzzling, and very distracting. Engine was running fine. Fuel P indicator fluctuated, as did manifold pressure indicator. Boot pump on had no effect.
I was VFR and close to an airport. Landed safely. Upon inspection the pin hole in the exhaust elbow was pointed at the firewall and a bunch of wires and lines.
In the end, that damage, along with the firewall and horsecollar were was such that the aircraft was scrapped. Total loss. In retrospect, the proper thing to do was shut down the engine, and assume the worst. Having indicator failures over the years, I did not make that choice, unfortunately. This incident happened me with some 10,000+ hrs, 75% of that in mulit engine piston, turbine nad jet aircraft.
Had I been farther from a VFR airport, or IFR, and given that the engine was running fine, good oil pressure and the rest, the exhaust could have easily burned through to the fuel tank in a very short time.
It could have ended much the same as this C414.

Yes all 400 series Cessna's had the same issues to change exhaust manifolds to Inconel back in the 90s. We had a 421B that was affected but sold it before any ADs were issued so I did not keep track after that. The video sure looked like a fire before/during the breakup. Too bad!
This is a link to very haunting video/audio from a Nestcam. Maybe someone here can gain some insight into what might have happened. https://www.reddit.com/r/flying/comments/amv511/plane_crash_yorba_linda_ca_developing/efq6rjo
That audio sounded like only 1 engine to me. I can't help thinking one wing might have failed at altitude. There was one report that radar showed it at 6000 or maybe it said 8000 feet then suddenly began to dive almost straight down. Hard to believe this was not some structural failure.

Sounds like it was in a steep dive at full power, maybe they were disoriented, broke through the cloud layer and saw the ground and pulled too hard. It sounds like the wing folded and broke off which is why the prop sounds like it hit something before stopping, and then pieces are raining down instead of just one impact area as if it broke up at a couple hundred feet.
