10. ~Maintenance Experience~
More than 30 years of operation in Kagoshima Airport, ANA has not experienced significant damages or problems for both engines and airframes due to volcanic ash from Sakura-jima.
Based on observation by Kagoshima Airport Meteorological Station, falling volcanic ash in Kagoshima airport has been reported for 67 days in 15 years from to
Unfortunately, actual quantity of falling ash has not been counted.
ANA’s 864 flights were operated (landings and take-offs) in the affected date and time.
Scheduled engine borescope inspections, engine overhauls and airframe inspections proved no significant damages or problems due to volcanic ash fall.

11. ~Maintenance Experience~
Falling ash date and time for last 15 years

12. ~Maintenance Experience~
For your reference, Kagoshima local Meteorological Observatory (11 kilomters (7 miles) west from Sakurajima) has monitored quantity of falling ash.

13. ~Operations near the active volcano~
ANA strongly believes that
Our operational experiences around Sakura-jima should be considered carefully to establish new guidelines and/or rules in ICAO Task Force.
Study for Sakura-jima is essential to establish new guidelines and a good opportunity since the volcano is still active and live.
