Test methods and measuring equipment

About measurement systems analysis; The IATF 16949: 2016 standard requires the following requirements.

7.1.5.1.1 Measurement systems analysis 

Statistical studies shall be conducted to analyze the variation present in the results of each type of inspection, measurement, and test equipment system identified in the control plan. The analytical methods and acceptance criteria used shall conform to those in reference manuals on measurement systems analysis. Other analytical methods and acceptance criteria may be used if approved by the customer. 

Records of customer acceptance of alternative methods shall be retained along with results from alternative measurement systems analysis (see Section 9.1.1.1). 

Note: Prioritization of MSA studies should focus on critical or special product or process characteristics

So as you know, an MSA study must be carried out for each type of instrument specified in the control plan. 
In other words, MSA is not required if measurement equipment is not defined in the control plan. If any automotive customer, in customer-specific requirements, is stated that there is an obligation to do MSA studies once a year; then MSA studies must be done once a year. 
But if there is no such request; as long as the measurement device does not change, malfunction or the device is changed; MSA is not required every year.

Briefly,

• MSA should be for every type of measuring instrument included in the control plan. Better have an MSA plan prepared.
• It is recommended to start with the critical product and process characteristics.
• There are also many methods for MSA. There is no only Gauge RR study, there are bias, linearity, stability, short method, ANOVA, GRR, attribute methods, destructive methods, etc..  
• The correct MSA method should be chosen according to the type of measurement system.
