Puerto Carreno cargo 722 crash
Certainly not familiar with that flap 30 procedure.
I understand the noise abatement aspect but what take-off performance effect does it have versus more "traditional" settings?

In fact, after the KSLC crash (1965?) my company blocked out Flaps 40. So, Flaps 30 became our landing flap setting. Some carriers didn't block them, but made Flaps 30 the normal landing flap.
For gearlever
Condensed translation of key points
First paragraph, according to CVR FDR during taxi T O check list done, radio call for local traffic done as airport was uncontrolled at the time
Second paragraph, aircraft backtracked for take off on Ray 25, after 180 turn aircraft was NOT aligned with runway, this was corrected during T O roll.
Third paragraph, aircraft was configured with 30 degree flaps ( as per note 7 ) with 6.5 units of elevator, crew did not consult latest METAR that was available at airport office.
Note 7 refers to the special modification for flap 30 T O
hope this helps

It doesn't. Probably because they aren't set to 30°.
The patent associated with the Quiet Wing mod specifies that the inboard flaps are re-rigged 7° down and the outers 3.5° (so around 5° down on average) so that the effective flap angle with 25° set is approximately 30°.
But I don't think the drooped angles are placarded as such, so it will still be nominally 25°.

Post # 143, 3rd paragraph next to red arrow states : based on CVR and FDR it was found that HK 4544 was configured for take off with 30 degrees of flaps and 6.5 units of elevator then it goes to state re METAR as previously translated.
Next to 30 degrees there is the note to refer to note seven below next to second red arrow.
It clearly states "HK4544 was configured with flap 30 for the take off"

Back on thread: I have never heard of Flaps 30 being an option for takeoff.

Spanglish
Regarding an earlier post, "copick" is Spanglish. Spanish does not have a real equivalent word for "cockpit". Officially, it is "cabina" or "cabina de piloto". Here in Cuba del Norte (Northern Cuba aka Miami), I have even heard it called cancha (kinda like court, as in tennis court). So, I don't think the use of Spanglish necessarily diminishes the accuracy of the remainder of the report.

According to the information provided by the flight recorders Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR), It was evidenced that the aircraft Backtracked towards runway 25 Threshold And simultaneously the crew performed the respective before takeoff checklists; as well as the self-announcement calls (blind) to the aircraft on the area, having in mind that the airport at the time was Uncontrolled.
Once the backtrack was completed , it was evidenced that the aircraft performed a 180 degree turn resulting in a heading different from runway heading, which was later corrected during the takeoff run.
Based on CVR and FDR, was identified that HK-4544 was set for a takeoff configuration of 30 degrees of flaps and 6 ½ (according to modification (STC)- ST00507SE “Flap and aileron droop modification- Quiet wing Corporation) units of stabilizer trim (up), also was found that the crew was unaware of the wind direction and intensity information. The closest takeoff time METAR was: 2200Z 01008KT 9999 FEW020 SCT200 32/31 A//// (This info was available on the IDEAM (Colombia’s meteorological department) office at the airport ).

KRE Designador IATA...Serious!!????
Such a credible report for sure, when one cant even know that 3 letter are ICAO and 2 are Iata...

I believe janetflight is referring to the AIRLINE or carrier code, not the airport code.
As in NZ (IATA) or ANZ (ICAO) for Air New Zealand.
AeroSucre S.A. (air carrier) - IATA: 6N, ICAO: KRE
Puerto Carreno (airport) - IATA: PCR, ICAO: SKPC (But not the codes in question)
However, one typo in a footnote is not exactly "definitive" of the quality of the report. Good Lord!
