Thirty five SOB, the aircraft crashed near the last reported position, but the wreckage wasn’t found for six months. It was 1969, not in the jungles of the Amazon, it happened in California.

Narrative:
The DC-3 aircraft left Hawthorne (HTH) at 03:50 PST on a VFR flightplan for Burbank (BUR) and Long Beach (LGB), USA. Last contact with the flight was at 04:06 when the crew contacted the Tonopah Flight Service Station, and requested that their flight plan be opened. At 05:10, some 20 km West of Lone Pine, the airplane impacted the face of a sheer cliff on the east slope of the Mount Whitney at an elevation of 11,770 feet m.s.l. (3587 m). The main body of the wreckage slid down the cliff and came to rest 500 feet back from the cliff.
An extensive ground and air search was launched after the aircraft was declared missing. Due to heavy snow accumulations on the ground, low clouds throughout the search period, and extremely hazardous terrain, the aircraft was not located until August 8, 1969.

Follow-up / safety actions

FAA issued 1

I took this photo at the Lone Pine airport about 10 years ago looking west towards the accident site.

The DC-3 remains on the mountain where it crashed but hikers to the site are kind of freaked out and don’t stay long. A lot of personal items like shoes and handbags litter the site. The USAF lost a helicopter at the site too.

I’ve worked 6 accidents and the only ELT’s I’ve ever heard have been from aircraft parked on the ramp
 
I’m guessing someone here knows the answer to this, but when were ELT’s required for 121 operations?

I’m pretty sure it was post 2001…?

It seems today's 91.207 was once 91.52, and 91.52 appears in this advisory circular from 1980, but the registry changed it to 91.207 in 1989. With a little more research, it wouldn't be too hard to find out when 91.207(F)(2) was adopted.


 
January 1st, 2004.

ALPA was advocating for ELTs in 121 aircraft going as far back as 1968 (with an official position paper in 1970). There was another one published in January 2001.

Thanks.

I was good friends with the pilot who wrote the 2001 paper but hadn’t heard when it was actually implemented.
