Embraer's E-Jets series have accumulated more than 23 million flight hours, and have achieved a dispatch reliability of 99.52%. Their goal is to have the E2 quickly reach operational maturity after entry into service and achieve the same level of success, with a goal of 99% dispatch reliability before 12 months in service. But how much of the experience carries over to an aircraft with virtually every system changed and improved, new engines, new avionics, and only 25% of the components the same as their E1 counterparts?
Embraer has taken a number of steps to "mature" the E2 and specifically chose to utilize their early schedule performance against the plan to continue to test and bring additional maturity to the E2 systems. Three specific actions were taken, including increased testing on the "iron bird", the creation of their in-house Pioneer Airlines operation, and action on airline customer suggestions on how to improve the E2 over the E1 models.
The Iron Bird
The "Iron Bird" is a mechanical representation of the systems of the aircraft laid out on a frame rather than enclosed in a fuselage or wings, fully visible to engineers who can observe and test individual components. These systems range from engines to hydraulics and operational landing gear to cabin air handling to avionics and electronics. Virtually every system on the aircraft is represented and tested in the "Iron Bird" to ensure the robustness of components and determine the proper intervals for service checks. On the E2, extensive testing led to the establishment of 1,000-hour intermediate checks and 10,000 shop visits, up from 850 and 8,500 respectively on the E1 models.
More than 45,000 hours of tests were completed on multiple system rigs, including more than 20 endurance tests on specific systems and components. More than 170 components had highly accelerated life tests performed, which enabled corrective actions after some of the components failed, thereby improving the durability of E2 systems.
Embraer has an advantage in that it...
