Robinson Helicopter on July 21 announced that R22 and R44 helicopters purchased after January 15, 2020, will be outfitted with Lycoming’s recently certified Electronic Ignition System (EIS). Robinson explains the EIS offers increased reliability, improved starting characteristics and reduced maintenance.

The EIS installation replaces the left starting magneto, according to Robinson, while the remaining right magneto provides redundant ignition and eliminates the need for a backup power supply. Robinson states EIS has very high spark-energy for easy engine starts and eliminates internal moving parts for increased reliability.

EIS is designed to last the life of the engine with no scheduled maintenance between overhauls, according to Robinson, eliminating the required 500-hour inspection. “The EIS will make the technician’s job easier and will help reduce unscheduled maintenance,” said Pat Cox, technical support supervisor, Robinson Helicopter.
