9/5/2014 - MACDILL AIR FORCE BASE, Fla. -- For
over 50 years, the KC-135 Stratotanker has been an integral part of the
world-wide aerial refueling mission...but from time to time, this aging
airframe needs minor touch-ups.
Recently, MacDill was selected as a pilot base for a new replacement part called the Improved Nose Wheel Snubber Brake.
The KC-135 uses a snubber brake system to eliminate noise and vibration
when the nose landing gear is retracted, which currently cost the Air
Force $350,000 in parts and labor every year on average.
Throughout the years, the brake arms have experienced fatigue cracks
around the mounting holes due to the limited surface area needed for
stress distribution. Subsequently, this part is typically replaced every
seven years due to the deficiency.
The Air Force Life Cycle Management Center/Legacy Tanker Division
designed the Improved Nose Wheel Snubber Brake to address this
deficiency by making the mounting portion of the spring arm thicker and
wider.
To coincide with the replacement, the Air Mobility Command Test and
Evaluation Squadron constructed a two phase Logistics Service Test,
which evaluates the operational effectiveness and suitability of the
INWSB.
The first phase, which occurred in August, consisted of the 6th MXG
personnel installing one set of INSWB arms. Phase two will consist of
normal aircraft operations with routine inspections for a period of six
months to include no less than 50 sorties. At the end of the testing
period, the INWSB arms will be removed and receive a thorough product
quality inspection.
With the success of this part the Air Force could potential save
$330,000 per year, per aircraft and remove certain inspections entirely.
