Rotatable aerodynamic fairing system

A fairing assembly comprising:

• a support arm mountable to a frame rail of a vehicle adjacent to a set of wheels;
• a fairing adapter adapted to mount a fairing to the support arm, the fairing adapter rotatably coupled to the support arm and rotatable from a first orientation corresponding to an aerodynamic position to a second orientation corresponding to a first access position in which the fairing is at least partially behind the support arm or in which the fairing is at least partially in front of the support arm, wherein the support arm and fairing adapter define a set of coaxial openings;
• a joint pin that passes through the set of coaxial openings, wherein the fairing adapter is rotatable relative to the support arm about the joint pin;
• and
• a releasable lock to lock the fairing adapter in the first orientation and releasable to allow the fairing adapter to rotate to the second orientation.

• and
• a releasable lock to lock the fairing adapter in the first orientation and releasable to allow the fairing adapter to rotate to the second orientation, the releasable lock comprising a locking pin, wherein the support arm defines a first locking pin opening positioned to align with the locking pin when the fairing adapter is in the first orientation and a second locking pin opening positioned to align with the locking pin when the fairing adapter is in the second orientation.
