Second mission is medical evacuation, aircraft recovery, fire fighting, parachute drops, heavy construction, civil development, disaster relief and SAR missions.

11. the Netherlands

The Royal Netherlands Air Force has 11x CH-47D and 6x CH-47F(NL) Chinook helicopters stationed with 298sq at Gilze-Rijen Air Force Base and with 302 squadron on Fort Hood, Texas, USA. Two CH-47D's crashed during deployment in Afghanistan.
The (D-versions) series D 661 till D 667 were bought from Canada after revision (airframe) till 0 (zero) flighthours and upgraded till CH-47D. The series D 101 t/m D 106 have been bought commercially by Boeing.

In 2007 all Dutch Chinooks got more armor in the cabin and in the cockpit.

The Dutch D-version Chinooks have a Dutch unique cockpit design. The chinooks from the Air Force of Singapore have almost the same cockpit.

 

New Chinooks for the Royal Netherlands Air Force
After the crash of 2 chinooks (tailnumber D-104 & D-105) and a need for more air transport the Dutch ministry of defence decided to purchase 6 new chinooks to a total of 11+6=17. They want to get a total of 20 chinooks but there isn't yet enough money. The problem is that the type chinook the RNLAF is flying with, is no longer produced anymore. Because of that, there have been studies to purchase the new CH-47F version with the same cockpit which is now used.

The Dutch Ministry of Defence has now ordered 6 CH-47F helicopters, worth 389.5 million euro's. Delivering is scheduled between july 2009 and january 2010. The Chinooks will be equipped with an Avionics Control and Management System (ACMS) Block 6 cockpit from Honywell.


NL Missions with the Chinook
- Dutch Chinooks are used in a lot of operations like: Kosovo and Iraq.
- On 25 February 2005 the Dutch cabinet decided without a decision of the Government to send 165 Dutch Special forces and 4 CH-47D Chinooks to South-Afghanistan.
- In support of the large mission of Dutch armed force to Uruzgan, a unknown number CH-47D chinooks were send to Afghanistan. More info soon.

Crash
- On july 27, 2005 a Dutch CH-47D Chinook crashed in the Afghan city Spin Buldak on the border between Afghanistan and Pakistan when it wanted to insert troops. The aircraft, one of two operating in the area at the time, was responding to reports of enemy activity.
The helicopter was not shot by enemy fire but by fire when the aircraft hit the ground. The crash was the result of "brown-out conditions". Brown-out conditions is when the rotor kick up dust and debris, reducing the pilots vision. This can occur dangerous landings. No one was injured in the incident.
- On 31 october 2005 a second CH-47D Chinook (D-104) from the Royal Netherlands Air Force was crashed 25 miles North-West of Bagram. The chinook was en route from Mazar-e-Sharif to Bagram air base. From the 17 passengers, 3 were injured and taken to the USA military hospital at Bagram Air Base. The others were taken to the Dutch detachment on Kabul International Air Port (KAIA).
The chinook could not be made anymore. That's why all usable parts have been removed. Then, on 13 november the remaining chinook have been destroyed with explosives.
