Abstract
A modular drainmast assembly for an aircraft includes a drain tube assembly removably enclosed in a fairing that is removably attachable to an aircraft. The electrically heated drain tube assembly may be accessed in the field for service, repair or replacement. A resilient sealed interface supports the drain tube where it exits the drainmast while permitting relative movement between the drain tube and the drainmast fairing due to thermal expansion and contraction.
Claims36
