You’d think they’d have a 100 unit value pack at Home Despot or Port Cargo.

I was expecting this retort, and boy do I love to prove people wrong on the internet. How about the fact that the meth head hacked open the fuselage with the axe first, so he had more room? Duh

This is slightly more plausible. The CRJ 200 (if full and it was summer time) can't really climb high enough that the pressure differential due to a giant ax cut in the aft fuselage would really effect things that much.
I'll believe it.

Update, appears to be incorrect takeoff speeds resulting in rotating too soon.

Incorrect speed record card caused 2024 Nepal plane crash, panel says
A passenger plane crash in Nepal last year that killed 18 people was caused by faulty information about the aircraft's takeoff speed in the flight documentation, a report issued on Friday by a government-appointed investigation panel said.

With only 18 pax and a very short flight? You’re already on the low side for V speed cards. Sounds like the excessive pitching was the main aggravating factor.

Crash: Saurya CRJ2 near Kathmandu on Jul 24 2024, rolled right and lost height after take off
Aviation Herald - News, Incidents and Accidents in Aviation

The contributory factors to the accident are:
- Incorrect speeds calculated based on erroneous speedcard. The interpolated speedcard of the operator for 18,500 kg TOW mentions incorrect V-speeds for take-off. This error in the speedcard went unnoticed since its development. There was no acceptance/approval of the speedcard booklet.
- Failure to identify and address multiple previous events of high pitch rate during take-off by the operator.
- The operator showed gross negligence in complying with the prevailing practices of ferry flight planning, preparation and execution. There is a lack of consistent definition of ferry flights.
- Gross negligence and non-compliances by the operator during the entire process of cargo and baggage handling (weighing, loading, distribution and latching), while violating the provisions of operational manual and ground handling manual. The load was not adequately secured with straps, tie-downs, or nets, while the flight preparation was rushed.

Damn, shut it down everyone. Cherokee Cruiser has it figured out YET AGAIN.
Be sure to share your findings with the Nepalese authorities. You’ll save them so much time and effort I’m sure.

That initial video looks fake. 90 degree bank to the right and then snap rolls wings level before impact? Seems AI to me.

Interesting that there was no mention of FDR data.

I HAVE STRONG OPINIONS ABOUT AUTOMOTIVE LIGHTING!
The report indicates that the FDR & CVR were readout by the Singapore TSIB.
It notes that indications for some flight control inputs were inop on the accident aircraft. Although the airline had acquired software for a flight data analysis function, they did not have an operating program, nor a program manager. However they did seem to have an archive of data back to 2021 which was included in the investigation's review(!).

The previous article mentioned the FDR. I often read threads backwards.

I’m not sure you read/understood my post?
Read again. They’re on the low side for the weight anyway.
The main problem is the 17.5kg and the 18.5 kg cards had the same data, that is obviously bad and shouldn’t happen.
But the actual VR used in the accident flight was 118 knots, when based on their actual weight VR should have been 122 knots. From having flown this plane before, 4 knots slower on VR should not result in a crash. Which is why I said it SOUNDS like the excessive pitch up and rate was the main problem for this crew.
And somehow your took that as I have figured out some black magic and should share with the Nepalese?
The investigators did their job. They found some speed cards had incorrect data. The main problem was their excessive pitch up and rate of doing so:
“
Specifically, investigators observed that flight crews consistently exceeded the standard pitch rate of 3 degrees per second during rotation.
One notable example was recorded on March 19, 2024, when the pilot-in-command of the accident flight had executed a takeoff with a peak pitch rate of 5.5 degrees per second.
In total, investigators identified 18 such instances on aircraft 9N-AME between 2023 and 2024, with pitch rates exceeding 4 degrees per second in all cases. The most extreme case occurred in January 2024, with a peak pitch rate of 5.8 degrees per second.
The March 2024 event involving the accident pilot-in-command represented the second-highest recorded pitch rate.
Excessive pitch rates during takeoff can result in a deep stall—a condition where the airflow over the wing is severely disrupted, leading to a loss of lift. This was consistent with the data observed during the accident flight. ”
