Overview
This service bulletin addresses the need for additional coolant liquid analysis for the TAE 125-02-125 engine used in Tecnam P2010 TDI aircraft. It outlines compliance requirements, acceptable coolant analysis ranges, and necessary actions if contamination is detected.
- Coolant analysis must be completed within the next 5 flight hours or during the next maintenance action.
- Further operation is not permitted until analysis results are available.
- Coolant contamination can lead to engine overheating and coolant loss.
- New limits for coolant analysis parameters have been established in this revision.
- If limits are exceeded, coolant system flushing and refilling is required.
- An extended FADEC download is necessary if coolant was exchanged in the last 50 flight hours.

Subject: Additional Coolant Liquid Analysis Type affected: TAE 125-02-125(CD-170) Models affected: all Classification: Category P1 - Safety Time of The coolant analysis shall be accomplished within the next 5 flight hours or with Compliance: the next maintenance action, whicheveroccurs first. Further Operation is not permitted until the results ofthe analysis are available. Only a FADEC data readout has to be carried out within the above-mentioned compliance time if the coolant has been exchanged during the last 50 flight hours. The coolant analysis has to be accomplished after the coolant has been used for 50 flight hours. Note: The acceptable ranges of the coolant liquid analysis have been tightened with Rev. 2 ofthis Service Bulletin. Silicon and glycolate have been added with Rev. 2 and 3 of this Service Bufletin. All analyses which have been carried out according to a previous issue ofthis Service Bulletin have to be reassessed relating to the new limits (except silicium). In case of exceeding the newly defined limits Continental Aerospace Technologies GmbH must be informed to coordinate further steps. Reason: In the cooling System, instances of coolant contamination have been detected, which may potentially lead to corrosion damage in the engine's coolant circuit. Consequently, this can result in coolant loss and engine overheating during Operation. Checked T. Kreißl,CVE l_ML Approved ( D.

Additionally, an extended FADEC download is required. (Red Wrench – FADEC Service Tool) In case of the coolant has been exchanged during the last 50 flight hours an extended FADEC download is sufficient, coolant sample must be taken after the coolant had been in use for 50 flight hours. When the TAE-125-02-125 engine is installed in a Tecnam P2010 TDI, SB 719- CS shall be applicable and a coolant system check must be performed in accordance with the relevant instructions (including dedicated Tecnam temporary revision or later approved AMM revision). If either aluminum or fluoride exceeds its limit, a cylinder head exchange is requested in accordance with RM-02-02, Chapter 72-30.13 Issue 5, Rev. 0 or later approved revision before refilling the coolant. Note: The acceptable ranges for aluminum and fluoride have been tightened with Rev. 2 of this Service Bulletin. Silicon and glycolate have been added with Rev. 2 and 3 of this Service Bulletin. Refer to Table 1 of Appendix A. Furthermore, if any other limit (see appendix A) exceeds the acceptable range, it is necessary to drain the coolant system, flush the coolant system and refill it with new coolant in accordance with the applicable engine and aircrafts Manuals to both eliminate contamination of the coolant and restore the anti-corrosion properties of the coolant. Note: The acceptable ranges for aluminum and fluoride have been tightened with Rev. 2 of this Service Bulletin. Silicon and glycolate have been added with Rev. 2 and 3 of this Service Bulletin.
