(2) Structure Checks 
% The DA 40 has been designed and tested under a 'damage tolerant structure' philosophy. % Therefore the structural inspections given in Chapter 05 cover all required structure checks. % There is no structural life limit. 
B. Replacement Requirements 
The replacement requirements under this paragraph are also included in Section 05-10. 
The following table lists life limited airplane components which must be replaced at a specific time. 
Where an interval is given in both flight time and calendar years, the limit which is reached first must be applied. 
VFR in the "Kind of Operation" column means that this limit applies to day VFR, night VFR and IFR operation. NVFR in the "Kind of Operation" column means that this limit applies to night VFR and IFR operation. IFR in the "Kind of Operation" column means that this limit applies to IFR operation.

C. Paint 
It is mandatory to paint the DA 40 white as described in Chapter 51 of this manual. This will prevent the temperature of the structure from becoming too high. Only certain areas which are defined in Chapter 51 of this manual (for example, registration markings, placards and warning markings) may have a different color. 
D. Repairs 
Repairs which are not described in Chapter 51 of this manual may only be carried out in accordance with a repair scheme which has been approved by the manufacturer or the competent National Airworthiness Authority. 
2. Continued Airworthiness 
Regular inspections of the airplane including replacement and overhaul of certain components are required to ensure Continued Airworthiness of the DA 40.
