SEATTLE, Nov. 16, 2010 /PRNewswire/ — A Boeing (NYSE: BA) Next-Generation 737-800 in the new United Airlines livery successfully completed its first test flight late last week, signifying the start of certification for a package of 737 performance improvements. Testing and certification will continue through April 2011. Aerodynamic and engine changes included in the package will reduce fuel consumption by 2 percent. Boeing is phasing the changes into production mid-2011 through early 2012.
One percent of the savings comes from reducing resistance as air flows around the airplane. The upper and lower anti-collision lights change from round to a more aerodynamic, elongated teardrop shape. Wheel-well fairings are re-contoured to smooth the air flow near the main landing gear. A redesign of the environmental control system, exhaust vent and streamlined wing slat and spoiler trailing edges round out the aerodynamic changes.
CFM is introducing the new CFM56-7BE engine enhancement program to coincide with Boeing’s airframe changes. Low- and high-pressure turbine modifications will result in a 1 percent reduction in fuel consumption. In addition, Boeing is optimizing the engine’s primary nozzle and plug. Together, the changes result in cooler-running engines that may provide up to 4 percent lower maintenance costs.

Boeing’s continuous efforts to improve the Next-Generation 737 family have resulted in an accumulated 5 percent gain in fuel efficiency since the first airplane was delivered in 1998. The new improvements will give operators an airplane that is 7 percent more efficient than the first Next-Generation 737s delivered.
In late October, Boeing delivered its first two Next-Generation 737-800s with the new Boeing Sky Interior. The interior features new cove lighting and curving architecture that create a more open feel in the cabin. Updated sidewalls and window reveals add a modern feel, and larger stowage bins enable passengers to store more luggage while giving them more headroom. Deliveries to new operators continue each month.

Narrative:
Iran Aseman Airlines Flight 6895 from Bishkek (FRU), Kyrgyzstan to Tehran (IKA), Iran was carried out by Itek Air. The Kyrgyz airline operated one of their Boeing 737-200 aircraft on that flight.
In the afternoon of August 24, from 16:30 to 20:00 local time, a thunderstorm with associated rain passed over Bishkek. Over that period the wind shifted from 220 degrees to 100 degrees at 20:30. Wind was blowing at about 6 kts, with wind variable at 23 knots. The temperature had dropped from 31 to 27 degrees C.
The weather then improved and at the time of departure visibility was more than 10 km with 6/8 clouds at an altitude of 5000 m (ca 16400 ft).
The Boeing 737 was cleared to taxy to runway 08 for departure. Take off was commenced at 20:30. The flight was cleared for a DW-1 departure, which entailed a left turn after takeoff to a heading of 240 degrees towards the RENAT beacon. From there it was to continue to the Chaldovar NDB, which should be crossed at or above FL158.
At 20:36:40, the airplane was climbing through an altititude of 3000m (almost 10.000 feet). At that moment the cabin altitude alert horn probably sounded, because the crew reported problems with the cabin pressure.
The crew decided to return to Bishkek and requested a visual approach to runway 08. This was approved and the airplane made a right hand turn, for a straight-in approach to runway 08. At 20:41:40 the crew reported the runway in sight. About 20:42:30 the flight was 12 km from the runway, flying at 400 m above airfield elevation at an airspeed of 460 km/h (250 kts). At a distance of 5 km from landing, the airplane had decelerated to 340 km/h (185 kts), but it was not properly configured for landing. The flight crew then obtained permission to carry out a left-hand orbit in order to configure the plane for landing. A left hand turn was flown with a 30-degree bank.
In the process of ther turn the aircraft descended further with the airspeed decreasing to 290 km/h (155 kts).
The airplane struck terrain some 7.5 km from the runway. At the time of impact the landing gear was down and flaps were selected down at 15 degrees. (src=http://aviation-safety.net/db)
