Subtask 33-48-00-710-063-A ** ON A/C NOT FOR ALL
A. Do a check of the aircraft logbook for entries related to the NEOL indicator.
(2) If there is not an entry related to the NEOL indicator, do the operational test of the strobe lights AMM 33-48-00-710-002.
Subtask 33-48-00-710-063-E ** ON A/C NOT FOR ALL NOTE: A forward-facing LED strobe light with NEOL indication is installed at the leading edge of each sharklet. The NEOL indication is a blue LED light that flashes when the LED light is near degradation and you must replace it by a serviceable light before 1000 flight hours. When the NEOL indication comes on, the LED light will not be extinguished after 1000 flight hours but its performance can decrease to less than the certification requirements.
(1) If there is an entry related to the NEOL indicator, follow the instructions. (2) If there is not an entry related to the NEOL indicator, do the operational test of the strobe lights AMM 33-48-00-710-002.

The NEOL indication is a blue LED light that flashes when the LED light is near degradation and you must replace it by a serviceable light before 1000 flight hours. When the NEOL indication comes on, the LED light will not be extinguished after 1000 flight hours but its performance can decrease to less than the certification requirements.
NOTE: The LED rear navigation and strobe light assembly (16LA), installed on the tail cone, has a LED light assembly and flashes at a rate of 60 plus or minus five flashes per minute. The NEOL indicator starts to flash when the light assembly is in the last 1000FH of its pre-programmed life. The light assembly will become unserviceable after its pre-programmed life.
(1) If there is an entry related to the NEOL indicator, follow the instructions. (2) If there is not an entry related to the NEOL indicator, do the operational test of the strobe lights AMM 33-48-00-710-002.

A. If the NEOL light continues flashing:
(1) For the forward-wing (sharklet) white strobe-light you can make the decision to do the light module replacement CMM 334839.
