B-737 Cargo Plane down in Hawaii

[India Four Two]

400’ is well beyond the range of SCUBA divers, but is achievable by commercial saturation-diving. That might be a cheaper option than raising the fuselage.

"The last turn was likely a turn to try to reach Kalaeloa Airport (JRF) - former NAS Barbers Point."

The NTSB will by now know, having interviewed the crew, whether or not that was the case.

[WHBM]

One wonders whether they actually got the lights turned on and saw them.

[nikplane]

I think perhaps no

[568]

I wonder what the insurance company will think and agree upon the possible salvage of the aircraft?

[DaveReidUK]

I can't imagine insurers having any interest in raising the wreck.

[procede]

I also doubt a 47 year old hull is really insured. The replacement value is probably less than a standard deductible.

[Sailvi767]

I am not saying this is what happened in this case but I was once told that it was important when attempting a relight with a hydro mechanical fuel control to insure that throttle was at idle. If you shut the wrong engine down by mistake and then threw that fuel control lever back up without retarding the throttle it might hang up at a low thrust condition with a big overtemp.

[568]

It would be interesting to see the cargo manifest to see if any DG was onboard?

[568]

Sailvi767

To reset the intake guide vanes, I believe that the fuel control switch(s) and thrust levers need to be in idle.

[Teddy Robinson]

They declared no DG on board.
Reporting hazard summary is SOP for freight operators.

Listening to the RTF recording in Post #48, the pilot states "We don't have any HAZMAT"

[tdracer]

DaveReidUK

Agreed - there is little value there other than as scrap metal once they recover the recorders.
IF it turns out that they did experience a dual engine power loss - and - they can't determine the likely cause (from FDR, maintenance records, etc.) the NTSB may want to raise the engines to see if they hold any clues.
Other than that, I think the sea life around Oahu were just gifted a new play area.

Doubt the state is happy with the wreck as it sits now (fluids, cargo) and may require some type of environmental remediation.

[Spooky 2]

I'll second that remark. Suspect there maybe some remedial fines associated with this accident.

[568]

This is an interesting site.

I don't know if the location will be an issue for the island(s) regarding the ditched 737 (fluids and cargo).

However there is a distinct difference between the two.

What is the difference between HazMat and dangerous goods?
The core difference that lies between dangerous goods and hazardous substances is that dangerous goods present an immediate danger to people, property and the environment, that may ultimately harm a person's health; on the other hand, hazardous substances are substances that present a direct risk to a person's health.

[568]

Thanks,
Didn't listen to the RTF.

Depends on the cargo, but after a couple weeks of a broken aircraft sitting on the seabed ~400 ft. down, it's too late to do much about any fluids...

Inter-operability of terms

568

Irrespective of the effect of "dangerous goods" vs "hazardous materials" on a person's health, the accepted terms for relay to ATC or upon a request by them to state carriage of, is either "DANGEROUS GOODS" or "HAZMAT". If ATC cannot figure that out, I am certain they will ask. Generally, associated with the DANGEROUS GOODS/HAZMAT notification, is information such as POB (or SOB), and fuel on board (pounds, kilos, tonnes - whatever the gauges are calibrated in).
