More properly, all we can say is that the trail is "waved." Whether this is a side view of a helix or a view of a flat wave cannot be determined from one photograph. Clearly, the trail commences as straight and increasingly acquires the "wave" in the portions of the trail that are "older," that is, have interacted with the upper atmosphere for a longer and longer time at the moment the photo was taken. This clearly implies that the "wave" is induced by a progressive interaction with the atmosphere. It may be more of a "plasma" or electrodynamic interaction than simple wind. The suggestion of an irregular or wobbling or spinning meteoroid is suspect, as material shed with varying lateral motion components would disperse into an irregular pattern much closer to the "head" of the trail than what is seen here.
