At first glance, although winglets may appear to be simple extensions of an aircraft’s fixed wingtips, they serve the specific purpose of reducing vortices that would otherwise generate drag and diminish aerodynamic efficiency. By managing these wingtip vortices more effectively, winglets contribute to measurable fuel savings, improved climb performance, and better handling. Like any functional part of an aircraft, they rely on consistent, properly executed maintenance to perform as intended. For your reference, this blog will first cover the common winglet types found on modern aircraft, then discuss maintenance intervals and procedures technicians should generally follow to preserve their airworthiness.
