Nuri Down II

KUALA LUMPUR: From the headlines below from Bernama, it is obvious that the search and rescue team have yet to locate the Nuri (Sikorsky Sea King S-61) which crashed into the jungles around Genting Highlands around 9.35am yesterday (July 13).

No Sign Of Copter As Aerial Search On Second Day Ends

Dense Forests, Steep Inclines, Thick Mist Hamper Copter Search.

It is obvious to everyone including Malaysian Defence that looking for a helicopter in dense jungles is almost impossible. Perhaps they could have installed a transponder of some kind.

But according to another report, the RMAF chief was quoted as saying: “Crew Transmitter Of Missing Copter Malfunctions placing the burden on the ground arch team.


Since the current transmitter failed perhaps the air force might want to look for this device instead or something similar:

ELB3000F AND EAS3000F Emergency Locator/Recorder System

Taking the Search Out of Search and Rescue

For over 25 years, DRS’s AN/URT-26 and AN/URT-43 Deployable Emergency Locator Transmitters (ELTs) have been providing unsurpassed search and rescue capability for P-3 crews around the world. DRS now offers two new Commercial Off-The-Shelf (COTS) upgrades to further improve on these mature, field-proven systems.
121.5/406 MHz Emergency Locator Transmitter (ELT) Upgrade
For P-3 operators wishing to upgrade their AN/URT-26 or AN/URT-43 ELT with the latest digital 406 MHz technology, DRS offers a form/fit replacement ELB3000F deployable ELT system. This beacon incorporates a COSPAS-SARSAT certified 121.5 MHz/406 MHz ELT providing all of the SAR enhancements of 406 MHz technology, including a Global Positioning System (GPS) position encoding interface that allows the ELT to transmit the aircraft’s last known latitude and longitude.
Deployable CVR/FDR Upgrade
For P-3 operators also requiring Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR), DRS offers an EAS3000F deployable ELT and CVR/FDR system. This upgrade is a solid-state crash recorder (housed in the beacon) and an aircraft monitoring unit (AMU) that interfaces to the aircraft’s avionics suite gathering audio and flight data inputs. The AMU can be further upgraded with software to incorporate Health and Usage Monitoring System (HUMS) functions. The HUMS subsystem is user modifiable, providing unsurpassed end-user flexibility and security.

Of course some might say its too late to install them as another Bernama report says “Govt Plans To Replace Nuri Helicopters – Najib .

But Malaysian Defence believes as long as the Nuri are in service, it is best that aircraft is equipped with the latest and greatest equipment, so we will know, if the unthinkable happens, what had happened and locate it within the golden hour so the crew, who survived the crash, could be saved.

Based on the literature from DRS Technologies, its CVR/ELT could be transferred easily to another aircraft. So when the Nuri is replaced, its CVR/ELT could be fitted to the replacement helicopter on one-to-one basis. If we buy more than the current Nuri fleet, simply buy new ones for these aircraft.
