        The possibility was studied that there might be some unknown phenomenon at work that could cause a reduction in structural stiffness with age. Such a reduction in stiffness could result in a reduced flutter speed and lead to flutter. In 2004, Airbus conducted GVT in support of its MRTT program. The testing was conducted on an aged A310 aircraft (MSN 523) that had accumulated over 28 000 flight hours. This test aircraft had the same design of VTP and rudder as the occurrence aircraft. GVT results found that fin bending and rudder rotation frequencies of the MRTT test aircraft were consistent with those obtained during the original A310-300 certification. No indication was found to suggest that stiffness had reduced with age.

        On the exhibition end, most of the sound heads in use at present slide the film past a stationary sound gate with the result that irregularities in the friction of the film against the gate produce a flutter. As a result of film shrinkage, only one pair of teeth in the pulling sprocket made contact with the film at one time. At the moment the pulling pair of teeth are disengaged from the film a slight slippage of the film is required to bring the next pair of teeth in contact with it. This results in a speed variation known as sprocket-hole modulation. Where a hold-back sprocket is not provided, variations in the tension of the takeup mechanism are transmitted directly to the pulling sprocket with resulting variations in speed.
